欢迎来到NCL语言学习指南!

NCL全称为NCAR Command Language，是由美国大气研究中心（NCAR）开发的 专门用于科学资料分析与可视化的一门解释型语言。

NCL支持的数据类型包括NetCDF 3/4，GRIB 1/2, HDF 4/5，HDF-EOS 2/5， shapefile，ASCII，binary。内建了大量的分析函数。可以很方便的产生 高质量的图形并且有大量的图形源（resource）可被用于自定义图形。大量 示例脚本和相应的图形可在官网（ncl.ucar.edu）学习。

本学习指南尝试通过一个更友好的方式将NCL语言知识提供给中国的NCL学习者。 如果你对本指南中的任何论述存在怀疑、困惑，或者在学习NCL过程中有任何问题， 欢迎到本项目GitHub的Issues页反馈以帮助改善本指南。

开始使用

命令行选项和参数

运行NCL时，可以使用一些选项来改变NCL解释器的默认行为。 同时给脚本传入命令行参数来指定程序中的变量值，这使得编写的脚本能够更加有效。

选项

NCL预定义的选项包括：

• -f : 在可能的情况下使用新的文件结构和NetCDF4特征
• -h : 打印此命名行选项帮助信息并退出
• -n : 使用print函数时，不显示元素序号
• -o : 对于某些向后不兼容的改变保留从前的行为
• -p : 关闭 system() 函数在页面上的输出
• -x : 回调NCL命令，进入命令行时将回调所有自动载入的函数（6.2.0版以上）
• -Q : 关闭NCL版本和版权信息显示
• -V : 打印NCL版本并退出

-h

$ ncl -h
  Usage: ncl -fhnopxQV <args> <file.ncl>
     -f: use new file structure and NetCDF4 features when possible
     -h: print this message and exit
     -n: don't enumerate values in print()
     -o: retain former behavior for certain backwards-incompatible changes
     -p: don't page output from the system() command
     -x: echo NCL commands
     -Q: turn off echo of NCL version and copyright info
     -V: print NCL version and exit

-n

参数

命令行参数是设定变量的简单的NCL语句，变量通过赋值定义。在赋值的等号 = 前后不允许有任何的空白。

例：以下代码赋值两个初始化变量 nyrStrt 和 nyrLast

% ncl nyrStrt=1900 nyrLast=2004

命令行中的快捷键

在命令行中运行NCL交互式运行时，有一些快捷键可以提升操作效率。 由于交互式运行经常运行测试脚本代码，掌握这些快捷键有助于克服 NCL交互式操作中的一些局限。 例如你想移动光标到行首，然而你会发现 Home 键无法使用时， 可能很崩溃，但你可以使用 Ctrl + A

控制字符

控制字符指的是使用 Ctrl 键和一些特定的英文字母来完成特定操作。

• Ctrl + A : 移动到行首
• Ctrl + B : 向左移动光标（左方向键）
• Ctrl + D : 删除光标所在字符
• Ctrl + E : 移动到行尾
• Ctrl + F : 向右移动光标（右方向键）
• Ctrl + G : 响铃
• Ctrl + H : 删除光标所在位置的前一个字符（退格键）
• Ctrl + I : 补全文件名（Tab键）
• Ctrl + J : 相当于回车键（回车键）
• Ctrl + K : 删除光标所在位置到行尾的所有字符
• Ctrl + L : 重新显示当前行
• Ctrl + M : 相当于回车键（回车键）
• Ctrl + N : 从历史命令中调出下一条命令（下方向键）
• Ctrl + P : 从历史命令中调出上一条命令（上方向键）
• Ctrl + R :
• Ctrl + T : 交换光标所在位置和前一个位置的字符
• Ctrl + V :
• Ctrl + W :
• Ctrl + X + X :
• Ctrl + Y :
• Ctrl + [ : 开始转义序列
• Ctrl + ] + C :

基础语法

了解NCL语言

许多的NCL初学者都通过学习范例的形式来开始NCL的学习，一些人甚至不屑于去看语法知识。 这样难免造成后续的一些恶果，经常是程序执行出行异常，却不知是何原因，事实上都是忽 视语法学习的后果。

NCL的语言十分简洁，甚至可以说有些简陋，所以学习起来并不十分费劲。我想大概也就是 几个小时的时间，就能让你有个较为全面的理解。

下面将要地介绍下NCL语言的特点

解释性语言

不同于C、Fortran等编译型语言需要首先将代码编译成目标代码才能被执行，NCL属于解释型 语言，代码是经过NCL解释器被逐条执行的。与编译型语言的目标代码执行效率相比，解释性 语言执行效率较低。然而解释性语言能实时修改代码，这点较编译型语言灵活。

动态类型语言

动态类型语言也就是说，你不要在赋值一个变量前声明变量的类型，当你赋值后，NCL解释 器将自动根据值的类型来确定变量类型。常见的动态类型语言还有Python、Ruby，或者你在 用的Matlab等等。

强类型语言

NCL同时还是强类型语言，也就是说一旦变量类型确定，除强制转换类型外，你无法改变变 量的类型。因此强类型语言是类型安全的语言。显而易见，强类型语言的在类型上的严谨性 能够有效的避免许多错误。

绘图

NCL绘图

高级图形接口

NCL语言中包含两类绘图函数，一类以gsn开头，另一类则以gsn_csm开头。 gsn_csm接口相较于gsn接口有更多的定制化的可视化风格，同时gsn_csm接口会尽可能的 利用绘图变量的元数据如 long_name, units 等等，自动地向图形中添加文本标记，因此 有更加智能化的特征。

gsn_csm接口定制化的特征包括：

• 经纬度刻度标签
• 地图图形中灰色填充陆地
• 基于元数据添加轴标签和标题
• 为填色等值线和矢量图添加色条
• 为极球面投影添加特殊标签
• 向外的刻度

设置等值线图层中等值线间隔的显示方法。

• AutomaticLevels 自动等值线阶

  Ordinarily this mode determines contour levels by picking a spacing value from a set of relatively “round” numbers scaled by powers of 10 to the range of the data. This set of numbers is as follows: 1.0, 2.0, 2.5, 4.0, 5.0. The number of levels chosen will be as close as possible to the value of cnMaxLevelCount without exceeding it. Once the spacing is chosen, the minimum contour level is set to the value of the least multiple of the spacing greater than the minimum data value. Likewise the maximum contour level becomes the greatest multiple of the spacing less than the maximum data value. Based on these values, ContourPlot sets the resources cnLevelSpacingF, cnMinLevelValF, and cnMaxLevelValF appropriately. On the other hand, if you explicitly set the resource cnLevelSpacingF to a valid value greater than 0.0 and less than the range of the data, it will be used as the interval spacing. The minimum and maximum levels are calculated as before. If as a consequence, cnMaxLevelCount is less than the number of levels so specified, it will be set to the number of levels actually needed. However, if the choice of spacing causes the absolute maximum number of levels, currently 255, to be exceeded, ContourPlot will issue a warning message and recalculate the spacing as previously described.

  In any case, ContourPlot sets the elements of the array resource cnLevels to the values of the contour levels chosen and the read-only resource cnLevelCount to the number of levels.

• ManualLevels 手动等值线阶

  ManualLevels mode bases the choice of contour levels on the values of the resources cnLevelSpacingF, cnMinLevelValF, and cnMaxLevelValF. Starting at cnMinLevelValF, contour levels are created at intervals spaced by the value of cnLevelSpacingF until cnMaxLevelValF is reached. The final contour level will always be cnMaxLevelValF. ContourPlot sets elements of the array resource cnLevels to the values of each contour level chosen and the read-only resource cnLevelCount to the number of levels. If the current value of cnMaxLevelCount is less than cnLevelCount, it is reset to the value of cnLevelCount. However, if the level count would exceed the absolute maximum number of levels, currently 255, ContourPlot issues a warning and chooses a new value of cnLevelSpacingF based on the value of cnMaxLevelCount. If you choose ManualLevels selection mode when the ContourPlot object is created, and if you do not set cnMinLevelValF, ContourPlot will choose levels as if you had set AutomaticLevels mode. If you set cnMinLevelValF only, a default spacing is used, and the value of cnMaxLevelValF is determined as it would be for AutomaticLevels mode.

• ExplicitLevels 显式自定义等值线阶

  这一模式允许你使用源 cnLevels 数组来显式地指定每一条等值线的值。如果 你选择此模式而不设定源 cnLevels ，等值线图将假定你指定使用自动等值线 阶模式，即 AutomaticLevels 来设定等值线阶。因此，当你设定 ExplicitLevels 模式时，不论你是否显式地设定了源 cnLevels ，等值线图都将使用当前的 cnLevels 的内容。如果源 cnLevels 的元素个数超过了等值线阶的最大 数量（当前为255条），等值线图将提出警告并设定模式回默认的自动等值线阶 （ AutomaticLevels ）。

  注意等值线图将总是对源 cnLevels 数组的元素排序为单调递增的序列。排序 后的数组，使用第一个元素设定 cnMinLevelValF ， 最后一个元素设定 cnMaxLevelValF ，元素间的间隔平均值设定 cnLevelSpacingF 。

• EqualSpacedLevels 等间隔等值线阶

  这种模式下，等值线图使用数据的最大值和最小值的差除以 cnMaxLevelCount +1 得到的值作为等值线的间隔。即设定 cnLevelSpacingF 等于计算的间隔，设定 cnMinLevelValF 等于数据最小值加上 cnLevelSpacingF , 设定 cnMaxLevelValF 等于数据最大值减去 cnLevelSpacingF 。

  你无法设定 cnLevelSpacingF cnMinLevelValF cnMaxLevelValF 。

  等值线图同时设定只读源 cnLevelSpacingF 等于 cnMaxLevelCount 。

默认值： AutomaticLevels

cnLevelSpacingF

当 cnLevelSelectionMode 设定为手动（ ManualLevels ）或者设为自动且设定了 cnLevelSpacingF 时， cnLevelSpacingF 决定了等值线的间隔。否则，等值线图 形对象将基于事实上选择的等值线阶来设定 cnLevelSpacingF 的值。当等值线阶选 择模式（ cnLevelSelectionMode ）设为显示自定义（ ExplicitLevels ）时， cnLevelSpacingF 将被设定到等值线间隔的算术平均值。

默认值：5.0

cnLevels

此源属性是一个包含等值线值的浮点型数组，被用于绘制等值线。如果等值线选择模式 （ cnLevelSelectionMode ）为显示自定义 （ ExplicitLevels ）时，你可以设 定此属性数组元素。否则，等值线图形对象将设定这个数组的元素。

默认值： <dynamic> 动态

cnLineColor

当等值线单线颜色属性 （ cnMonoLineColor ）被设定为真（ True ）时， 这个源属性接受一个NhlTColorIndex类（即颜色表序号）或者命名颜色（字符串）来为所有的等值线 设定一个统一的颜色。

默认值：Foreground (1) 背景色

cnLineColors

The elements of this array of type NhlTColorIndexGenArray can be set using an array of color indexes, an array of named colors, or an array of RGB or RGBA values. If cnMonoFillColor If cnMonoLineColor is False, each member of the array specifies the color of the contour line drawn at the corresponding contour level. Although backwards compatibility is for the most part maintained, beginning with version 6.1.0, this resource supports the new 32-bit color model, as follows:

If cnLineColors is not set explicitly, its values are derived from the settings of cnLinePalette and cnSpanLinePalette, or, if cnLinePalette is not set, wkColorMap and cnSpanLinePalette. If cnSpanLinePalette is True, the values are distributed evenly through the range of colors available from cnLinePalette or wkColorMap. Otherwise, the values are sequential. If the color indexes are derived from cnLinePalette the first color comes from element 0, whereas if they are derived from wkColorMap, the first color comes from element 2. This is because wkColorMap contains special elements (0 and 1) for the Background and Foreground colors, whereas the palette-type resources do not. If some but not all of the available elements of cnLineColors are explicitly set, the remaining elements will be determined as if cnSpanLinePalette has the value False.

For backwards compatibility, colors set based on wkColorMap remain indexed to the current color map associated with the workstation. Consequently, if the workstation color map is changed prior to drawing the plot, the color indexes will map into the new color map. In contrast, color indexes derived from the cnLinePalette resource always refer to a specific color regardless of changes to wkColorMap.

lbAutoManage

The lbAutoManage switch determines how LabelBar operates; when True, LabelBar manages the sizing of the title and the label text. The title is always sized to fit within the currently set boundaries of the LabelBar given any text angle, aspect ratio, etc. The labels also are sized to fit within the current boundary. Additionally, the sizing of the labels is managed so that under any rotation, the labels will not overlap. Also the label justification is managed such that, given any rotation, the end of the label string aligns with the correct LabelBar box. When off, you may directly size the labels and text as you please. However, under rotation, the justification of the labels does not change, and, although the text is moved out of the way of the LabelBar boxes, it will not necessarily line up correctly. In practice, when working interactively, a good method is to create a basic LabelBar layout close to the desired size with the lbAutoManage mode on, then switch it off to tune the text size precisely to your taste. Currently, when the text of the labels is rotated, the size of the LabelBar may increase slightly along the axis of orientation.

默认值: True

lbBottomMarginF

Defines an offset, specified as a fraction of whichever LabelBar axis is smallest, between the bottommost LabelBar element and the bottom edge of the LabelBar perimeter. It is always subtracted from the current LabelBar extent. Negative values are allowed.

默认值: 0.05

lbBoxCount

Number of boxes in the labelbar. All the LabelBar array resources, when specified, are required to have a number of elements related to the number of boxes. The arrays specified by lbFillPatterns, lbFillColors, and lbFillScales must have at least as many elements as the box count. The minimum size of the lbLabelStrings array may be the box count, one element less than box count, or one element more than box count, depending on the setting of the lbLabelAlignment resource. The lbBoxFractions array, when set, always requires one element more than box count. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: 16

lbBoxEndCapStyle

This resource controls the shape of the two outer boxes of the LabelBar, which may be either rectangular (like the interior boxes) or triangular/arrow shaped. Set it to one of these four values: RectangleEnds TriangleLowEnd TriangleHighEnd TriangleBothEnds

默认值: RectangleEnds

NOTE: this resource should be ignored if the contour resource cnLabelBarEndStyle is set to “ExcludeOuterBoxes”.

lbBoxFractions

An array that specifies sizing of each box in the LabelBar when the box sizing mode is set to ExplicitSizing. There must be one more element in this array than the number of items specified by the resource lbBoxCount. Each element of the array must eventually contain a number in the range 0.0 to 1.0, with succeeding elements increasing monotonically. The first element must be 0.0 and the last 1.0. If invalid values are discovered when the array is checked, it is not considered an error. Instead, the code simply supplies linearly interpolated values for all adjacent elements containing out- of-bounds elements. The interpolation is performed relative to the two closest bounding elements containing valid values, or 0.0 or 1.0 respectively if the first or last element contains invalid data. The values thus obtained represent the beginnings and endings of the LabelBar boxes.

默认值: NULL

lbBoxLineColor

The hlu index of the color used to draw lines around the boxes in the LabelBar

默认值: Foreground

lbBoxLineDashPattern

The hlu index of the dash pattern used for the lines around the boxes of the LabelBar.

默认值: 0

lbBoxLineDashSegLenF

The length in NDC units of the dash pattern used for the lines around the boxes of the LabelBar.

默认值: 0.15

lbBoxLineThicknessF

确定环绕色条框的线的粗细。

默认值: 1.0

lbBoxLinesOn

布尔型标记，用于控制环绕色条框的线条是否出现。

默认值: True

lbBoxMajorExtentF

Determines the amount of the area allotted to each box of the LabelBar in the direction of lbOrientation is actually occupied by the box. When set to 1.0, the boxes touch each other. If set to 0.0, the boxes disappear entirely. Intermediate values create separated boxes.

默认值: 1.0

lbBoxMinorExtentF

When the lbAutoManage feature is turned on, this resource determines the fraction of the distance (less the margins) across the axis perpendicular to the orientation (the minor axis) occupied by the boxes of the LabelBar. If set to 1.0, the boxes entirely crowd out their associated labels. If lbTitlePosition is set to a side parallel with the major axis, the lbBoxMinorExtentF cannot exceed 1.0 minus the amount of space used for the title, as set by the resource lbTitleExtentF. When lbAutoManage is False and lbTitlePosition is set to a side perpendicular to the major axis, the axis extent from which the box minor extent is calculated includes any extra extent added due to an increased value given to lbTitleFontHeightF. However, it does not include extra extent due to increased value given to the lbLabelFontHeightF resource.

默认值: 0.33

lbBoxSeparatorLinesOn

Available in version 6.2.0 and later. If this resource is set to False, it will draw a labelbar with no interior box lines (box separator lines), and just a perimeter line around the “bar” of the labelbar.

默认值: True

lbBoxSizing

When set to UniformSizing, all the boxes in the LabelBar have the same size. When set to ExplicitSizing, the values in the array, lbBoxFractions, determine the relative size of each box along the major axis (the axis of orientation).

默认值: UniformSizing

lbFillBackground

The color index used for the background of all the boxes in the LabelBar. By default it is set to Transparent (-1), specifying that the background of the boxes is transparent to whatever it overlays. Note that the box background is only observable when the fill pattern is not solid. This resource also applies to the background of the fill pattern set with the lbPerimFill resource.

默认值: Transparent

lbFillColor

When lbMonoFillColor is set True, this resource of type NhlTColorIndex sets a uniform fill color for all the LabelBar boxes. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: Foreground

lbFillColors

This array resource of type NhlTColorIndexGenArray individually sets the color of each box in the LabelBar when lbMonoFillColor is set False. The LabelBar ensures that this array contains at least as many elements as the current value of lbBoxCount. You may cause a box to appear empty by setting the appropriate array element to the value Transparent. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: By default, each box is assigned to the next succeeding color in the hlu color table, up to the number of defined colors. Additional boxes are assigned the current value of wkForegroundColor.

lbFillDotSizeF

This resource sets a uniform dot size, in NDC units, for the stipple dot fill pattern. The default value of 0.0 causes the dots to be drawn as before, using a workstation dependent minimum dot size. A caveat is that individual dots are not clipped around the edges of fill areas; this becomes more noticeable as the dot size increases.

默认值: 0.0

lbFillLineThicknessF

The line thickness used for the lines that comprise the fill pattern within the label boxes.

默认值: 1.0

lbFillPattern

When lbMonoFillPattern is set True, this resource of type NhlTFillIndex sets a uniform fill pattern for all the LabelBar boxes. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: SolidFill

lbFillPatterns

This array resource of type NhlTFillIndexGenArray individually sets the fill pattern of each box in the LabelBar when lbMonoFillPattern is set False. The LabelBar ensures that this array contains at least as many elements as the current value of lbBoxCount. You can cause any box to appear empty by setting the appropriate array element to the value HollowFill (-1). Note that you can use the scalar resource lbFillBackground to set a uniform solid-fill background color the fill patterns. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: All array elements above those specified by the user are assigned values according to the formula: element_index MOD wkFillTableLength + 1.

lbFillScaleF

When lbMonoFillScale is set True, lbFillScaleF sets a uniform fill scale that applies to all patterns in the LabelBar boxes. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: 1.0

lbFillScales

When lbMonoFillScale is False, each element of this array resource contains an individual scale value that is applied to the pattern assigned to the corresponding box in the LabelBar. When the scale value is 1.0, all lines in the currently defined patterns are nominally spaced at about 0.01 NDC units. The scale value is applied as a factor to this spacing. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: 1.0 for all elements

lbJustification

When the labelbar changes size, the justification determines a fixed point about which the size change occurs. Any of the corners, the center of any edge, or the current center of the LabelBar may be set to the fixed justification point. This resource may be intercepted or disabled by:

PlotManager

默认值: BottomLeft

lbLabelAlignment

How the labels align with respect to the label boxes. If set to BoxCenters, the labels align with the centers of each box, and the number of labels is equal to the number of boxes. If set to InteriorEdges, the labels align with the internal separators between the boxes, and there is one fewer label than the number of boxes. If set to ExternalEdges, the labels align with the external edges as well as the interior separators between the boxes, and there is one more label than boxes. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: BoxCenters (InteriorEdges in gsn_xxxx_xxx scripts)

lbLabelAngleF

The angle of the text of the labels. When the auto-manage resource is turned on, both the size and justification mode of the label text may change in response to changes of the label angle.

默认值: 0.0

lbLabelAutoStride

When this boolean resource is set True, LabelBar labels are checked for overlap before being drawn. If overlap would otherwise occur, a stride is set through the labels such that overlap will be avoided. The stride proceeds in both directions from a pivot label, chosen based on how “round” it is relative to the other labels. If the labels seem to be equally “round” or if the labels are non-numeric, then the shortest label is chosen as the pivot. If lbLabelAlignment is set to ExternalEdges, the behavior is a bit different. In this case, the stride is set as described above, but the labels at each end are guaranteed to appear. This may cause labels that would otherwise be part of the stride sequence to be eliminated. This behavior is useful when the end labels are used to show the extreme values of a dataset.

The stride calculated as a result of setting lbLabelAutoStride is independent of the stride specified by the lbLabelStride resource and is applied subsequently to it. Also note that lbAutoManage must be set False in order for lbLabelAutoStride to have an effect. When lbAutoManage is True, the label font height is reduced to avoid overlap and therefore a stride greater than unity is never required.

默认值: False (will default to True in V6.1.0 and later)

lbLabelBarOn

用于确定色条是否出现的布尔型标记。 A boolean flag that determines whether the LabelBar should appear. Primarily useful as a forwarded resource when the LabelBar is a child of a higher level object.

该源属性可被 PlotManager 对象捕获或禁用

默认值: True

lbLabelConstantSpacingF

Normally when lbLabelFontQuality is set to High, theLabelBar writes line label text with proportional spacing. Setting the lbLabelConstantSpacingF to a value greater than 0.0 overrides this behavior and instead begins each character a distance of lbLabelConstantSpacingF times the nominal character size from the beginning of the previous character. This implies that values between 0.0 and 1.0 will cause the characters to overlap each other, while a value of 1.0 implies no space between two nominally sized characters. This parameter is ignored when lbLabelFontQuality is not Low or Medium. Values less than 0.0 result in an error and are replaced with the default value.

默认值: 0.0

lbLabelDirection

This resource of type NhlTTextDirection specifies the direction of the label text.

默认值: Across

lbLabelFont

This resource of type NhlTFont specifies the font used to render the LabelBar labels.

默认值: “pwritx”

lbLabelFontAspectF

Determines the shape of the label font text. Values greater than 1.0 make the text tall and skinny. Values less than one make the text short and wide.

默认值: 1.0

lbLabelFontColor

The hlu color index used for drawing the label text.

默认值: Foreground

lbLabelFontHeightF

The height in NDC coordinates of the text used to draw the labels. When lbAutoManage is set True, the user cannot directly set the label font height. Rather, it is set in response to other factors, such as the current size and shape of the LabelBar, the current setting of lbBoxMinorExtentF, the current text angle of the labels, and how much space there is between the labels. Set lbAutoManage False if you wish to control the label font height directly.

默认值: 0.02

lbLabelFontQuality

确定绘制色条标签文本的字体质量。

默认值: High （高）

lbLabelFontThicknessF

设定用来绘制色条标签文本线的粗细。它的值为一个单位粗细（依赖设备）的倍数。 当色条标签字体源属性 lbLabelFont 设为填充字体（字体索引号 21-22， 25-26, 29-30, 33-37）时， 该源属性被忽略。

默认值: 1.0 （1.0倍）

lbLabelFuncCode

Determines the function code character used when parsing the label string. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: :

lbLabelJust

指定色条标签文本的对齐方式。当自动管理特征开启时，为响应色条标签文本的角度变化，对齐方式可能会内在地改变。 因此，为了显式地控制色条标签文本对齐方式，你应该首先关闭自动管理特征。

默认值: CenterCenter （上下居中，左右居中）

lbLabelOffsetF

Defines an offset, specified as a fraction of the length of the minor labelbar axis (perpendicular to the axis of orientation), between the LabelBar boxes and the labels.

默认值: 0.1

lbLabelPosition

这一NhlPosition类型的源属性控制标记（labels）相对于色条框的位置。 当色条的方向为水平，其有效值为 Top （顶）， Center （中）， Bottom （底）。 当色条的方向为垂直，其有效值为 Left （左）， Center （中）， Right （右）。 如果对应色条方向设置，设置的不恰当，此源属性的值将会轻微改变： Bottom （底）变为 Left （左）， Top （顶）变为 Right （右），反之亦然。

When set to Center the labels are centered on, and when the auto-manage feature is on, sized to fit within, each respective label box.

默认值: Right （右）

lbLabelStride

控制色条上的标记（labels）的间隔（步长）。如设置为2时，色调标记将每隔一个色块 画一个。

默认值: 1

lbLabelStrings

数组源属性，是构成色条标记（labels）的字符串数组。 此源属性可能被以下对象拦截或禁用：

ContourPlot (见 cnExplicitLabelBarLabelsOn)

VectorPlot (见 vcExplicitLabelBarLabelsOn)

StreamlinePlot (见 stExplicitLabelBarLabelsOn)

默认值: Label_<label element number>

lbLabelsOn

布尔类型的标记，用于控制是否将标记（labels）显示在色条下

默认值: True

lbLeftMarginF

Defines an offset, specified as a fraction of whichever LabelBar axis is smallest, between the leftmost LabelBar element and the left edge of the LabelBar perimeter. It is always subtracted from the current LabelBar extent. Negative values are allowed.

默认值: 0.05

lbMaxLabelLenF

This read-only resource returns the maximum length in NDC of the strings used as LabelBar labels.

默认值: <dynamic>

lbMinLabelSpacingF

This read-only resource returns the minimum distance in NDC from the start of one label string to the start of the next label string.

默认值: <dynamic>

lbMonoFillColor

When set True, all LabelBar boxes are set to a single color, as specified by the value of the scalar resource lbFillColor. When False, the elements of the array resource lbFillColors control the color of each box individually. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: False

lbMonoFillPattern

When set True, all the boxes in the labelbar are set to a single pattern, as specified by the value of the scalar resource lbFillPattern. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: False

lbMonoFillScale

When set True, the patterns applied to each box in the LabelBar are scaled by a single factor, as specified by the value the scalar resource lbFillScaleF. This resource may be intercepted or disabled by:

ContourPlot VectorPlot StreamlinePlot

默认值: True

lbOrientation

This resource of type NhlTOrientation specifies whether the labelbar boxes are arranged horizontally in a row or vertically in a column. The major axis of the LabelBar instance is parallel to the orientation and the minor axis is perpendicular to the orientation. This resource may be intercepted or disabled by:

PlotManager

默认值: Vertical

lbPerimColor

The hlu index of the color used for the line around the perimeter of LabelBar.

默认值: Foreground

lbPerimDashPattern

Specifies the hlu index of the dash pattern used to draw the perimeter of the LabelBar.

默认值: 0, specifying a solid line

lbPerimDashSegLenF

The length in NDC units of the dash pattern used to draw the perimeter of the LabelBar.

默认值: 0.15

lbPerimFill

The hlu index of the pattern used to fill the background of the LabelBar area. Only has an effect when the lbPerimFillColor has set to a value greater than Transparent (-1).

默认值: HollowFill

lbPerimFillColor

The hlu index of the color used to fill the background of the Legend area. Only has an effect when the lbPerimFill has a value greater than HollowFill (-1).

默认值: Background

lbPerimOn

A boolean flag determining whether a line is drawn around the perimeter of the LabelBar.

默认值: True

lbPerimThicknessF

Specifies the thickness of the line used to draw the perimeter of the LabelBar.

默认值: 1.0

lbRasterFillOn

If set True, this resource causes the LabelBar to use raster mode fill rather than normal polygon fill to render the box colors. In this case, only solid fill is possible; the fill pattern resources are ignored. If any element of lbFillColors is set to Transparent or lbBoxSizing is set to ExplicitSizing, raster mode fill is not possible: LabelBar issues a warning and defaults to normal polygon fill. Normally, assuming the boxes are solid-filled, the appearance of the LabelBar boxes will be identical whether or not this resource is set. It only makes a difference when the output must go to certain printers that render colors slightly differently when raster fill is in effect. ContourPlot forces lbRasterFillOn to True when it manages a LabelBar and raster fill is in effect.

默认值: False

lbRightMarginF

Defines an offset, specified as a fraction of whichever LabelBar axis is smallest, between the rightmost LabelBar element and the right edge of the LabelBar perimeter. It is always subtracted from the current LabelBar extent. Negative values are allowed.

默认值: 0.05

lbTitleAngleF

The angle of the title text. When the auto-manage feature is on, the title size changes as the text rotates.

默认值: 0.0

lbTitleConstantSpacingF

Determines a constant amount of extra space that is placed between each character of the title text. Values less than 0.0 result in an error and are replaced with the default value.

默认值: 0.0

lbTitleDirection

This resource of type NhlTTextDirection specifies the direction of the title text. When the title position, as set by the resource lbTitlePosition, is Top or Bottom the direction is set by default to Across. When title position is Left or Right the text is set by default to Down.

默认值: Across

lbTitleExtentF

The LabelBar title occupies a rectangular portion of the LabelBar viewport bounded on three sides by edges of the viewport and on the fourth by a line determined by the value of this resource. lbTitleExtentF specifies a fraction of the length (minus the margins) of the LabelBar axis perpendicular to lbTitlePosition. At this point along the length of the axis the fourth side of the title extent rectangle is constructed parallel to the side specified by lbTitlePosition. The sum of the values given to lbTitleExtentF and lbTitleOffsetF cannot exceed 0.5 (half the length of the axis). If the sum does exceed 0.5, a warning is issued and both values are reset to their default values. If lbAutoManage is set False, and lbTitleFontHeightF is set such that the title extent rectangle cannot accommodate the full extent of the title text, the viewport of the LabelBar instance is expanded to fit the title text extent. However, the LabelBar treats this additional extent as ‘extra’. The title extent rectangle does not change its size as long as the LabelBar view width or height is not explicitly modified. This means that as you set lbTitleFontHeightF to smaller values, the LabelBar viewport will shrink until its size matches the size it would have had if the text extent fit within the originally set title extent.

默认值: 0.15

lbTitleFont

This resource of type NhlTFont specifies the font used to render the LabelBar title.

默认值: “pwritx”

lbTitleFontAspectF

Determines the shape of the title font text. Values greater than 1.0 make the text tall and skinny. Values less than one make the text short and wide.

默认值: 1.0

lbTitleFontColor

The hlu index of the color used for the title text.

默认值: Foreground

lbTitleFontHeightF

The font height in NDC units used for the title text. If lbAutoManage is set True, the LabelBar sets this resource automatically based on the space available and the value of other title font attributes including lbTitleAngleF, lbTitleConstantSpacingF and lbTitleFontAspectF. The available space is determined from the size of the LabelBar viewport and the setting of the resource lbTitleExtentF. When lbAutoManage is True, attempts by the user to set this resource are simply ignored. If lbAutoManage is False, the LabelBar instance will honor the set value of lbTitleFontHeightF, even if it must increase the size of the viewport in order to encompass the full extent of the title text. However, space added in this manner is considered an addition to the ‘fundamental’ size of the LabelBar. If the lbTitleFontHeightF is reduced to a value less than or equal to the value that would be used if lbAutoManage were True, then the LabelBar will resize itself to its ‘fundamental’ size. If you resize the LabelBar by setting the width or height of its viewport, lbTitleFontHeightF and the ‘fundamental’ size both adjust themselves proportionally.

默认值: 0.025

lbTitleFontQuality

Determines the text quality used to draw the title text.

默认值: High

lbTitleFontThicknessF

Determines the thickness of the line used to draw the Label text. This resource only affects the Hershey fonts.

默认值: 1.0

lbTitleFuncCode

Determines the function code character used when parsing the label string.

默认值: :

lbTitleJust

The justification used for the title text.

默认值: CenterCenter

lbTitleOffsetF

This resource defines an offset specified as a fraction of the length of the axis (minus the margins) perpendicular to the side specified by lbTitlePosition. This offset separates the title extent, as specified by lbTitleExtentF, from the other elements of the LabelBar.

默认值: 0.03

lbTitleOn

A boolean flag determining whether the title should appear in the LabelBar. If lbTitleString is set when the LabelBar object created, lbTitleOn defaults to True. Otherwise it defaults to False.

默认值: True

lbTitlePosition

This resource of type NhlTPosition determines the position of the title with respect to the other elements of the LabelBar. Valid positions are Top, Bottom, Left, and Right. When you set the title position, LabelBar automatically adjusts the title direction, unless you explicitly set lbTitleDirectionin the same call. When you set the position to Top or Bottom, the title direction is set to Across; when the position is set to Left or Right, the title direction is set to Down.

默认值: Top

lbTitleString

A string containing the text used for the LabelBar title. If lbTitleString is set when the LabelBar object created, the boolean resource lbTitleOn defaults to True, causing the title to appear. Otherwise it defaults to False. If you explicitly set lbTitleOn True without setting lbTitleString, LabelBar supplies a title consisting of the name of the current instantiation of the object.

默认值: <dynamic>

lbTopMarginF

Defines an offset, specified as a fraction of whichever LabelBar axis is smallest, between the topmost LabelBar element and the top edge of the LabelBar perimeter. It is always subtracted from the current LabelBar extent. Negative values are allowed.

默认值: 0.05

视图源属性

vpAnnoManagerId

If the View object is currently functioning as an external annotation of a Plot Object, this read-only resource contains the id of the AnnoManager object used to manage the View object’s location and size. If the View object is not currently an annotation, the value of the resource is set to NullObjId (0).

默认值： False

vpClipOn

When this boolean resource is set True, all content elements of a plot object are clipped at the viewport boundaries. Setting it False allows plot elements that are not internally constrained to fall with the viewport to appear outside the viewport boundaries. Currently only VectorPlot objects allow any plot elements to appear outside the viewport. Note this resource does not apply to plot annotations such as tick marks and titles.

默认值： True

vpHeightF

vpHeightF 指定了视图对象边界框的高度（页面坐标（NDC））

默认值： 0.6

vpKeepAspect

当布尔类型的源属性 vpKeepAspect 为 True 时，视图对象将保持它的初始形 状（宽高比）。你仍然可以更改他的大小源属性。如果你同时更改大小源属性、 vpWidthF 、 vpHeightF While the boolean resource vpKeepAspect is True, the View object keeps its initial shape (aspect ratio); however you may modify its size resources. If you modify either or both the size resources, vpWidthF and vpHeightF, View will constrain its new bounding box to the largest box with an aspect ratio matching the original shape that can be inscribed within a box of the specified size. When vpKeepAspect is False, View places no constraints on the shape of its bounding box when you modify the size resources.

默认值： False

vpOn

设定 vpOn 为 False 将禁用视图对象的绘图方法（ Draw ）。当绘图方法 被禁用后，视图、视图类的子类、它的叠加图层（ overlays ）、以及它增加的标 注 （ annotations ）不会出现在工作站，直到 Draw 被执行。

默认值： True

vpUseSegments

When the boolean resource vpUseSegments is set True for a View class object, the object will, if it is able, create a segment and draw into it while it draws to the designated Workstation object. The segment is stored as a file, and contains the low-level commands required to re-create the object, possibly with transformations to the position, size, or shape applied. When you next draw the object, assuming none of the object’s resources other than vpXF, vpYF, vpWidthF, or vpHeightF have been modified, it will recreate its image based on information stored in the segment. Using segments can substantially shorten the time required to perform a draw when the plot contains elements, such as filled maps, that require considerable computation to generate initially. Note that because the transformations differ slightly, a segment drawn at a different size from the size at which it was created may not match in every detail the plot resulting from a new draw of the object at that size.

默认值： False

vpWidthF

vpWidthF 指定了视图对象边界框的宽度（页面坐标（NDC））

默认值： 0.6

vpXF

vpXF 指定了视图对象边界框的左边界在页面坐标（NDC）中的位置

默认值： 0.2

vpYF

vpYF 指定了视图对象边界框的上边界在页面坐标（NDC）中的位置

默认值： 0.8
