Color

Add a color expression attribute to add a coloring to the shapes defined by a plot.

model.result(<pgtag>).feature(<ftag>).create(<atag>,"Color");

model.result(<pgtag>).feature(<ftag>).feature(<atag>).set(property, <value>);

model.result(<pgtag>).feature(<ftag>).create(<atag>,"Color") creates a color expression attribute named <atag> belonging to the plot feature <ftag>.

Use color expressions to add a coloring to the shapes defined by a plot. Color expressions can be added to surface plots; line plots; volume plots; arrow plots; contour plots; isosurface plots; particle tracing plots; and streamline, streamline multislice, and streamline surface plots.

The following properties are available:

Table 7-18: Valid Property/Value Pairs for Color
Property	Value	Default	Description
colordata	expr \| arrowlength	expr	Whether to color the arrows using an expression in expr (set to expr) or using the arrow length (set to arrowlength). This property is only available if the Color attribute is added to an arrow plot or a trajectory plot where pointtype is set to arrow.
coloring	colortable \| gradient	colortable	Whether to use a color table or a color gradient.
colorlegend	on \| off	on	Whether to show a color legend.
colorscalemode	linear \| linearsymmetric \| logarithmic	linear	Scaling of the color table: linear, linear symmetric around 0, or logarithmic.
colortable	color table name	Rainbow	The color table to use. See Color Tables for a list of color tables.
colortabletrans	none \| reverse \| nonlinear \| nonlinearsymmetric	none	Transformation of the color table.
descr	String	Model dependent	The description of the expression in expr. Is used in the automatic title.
descriptionintitle	on \| off	on	Whether the title contribution should contain the description when titletype is custom.
differential	on \| off	on	Whether the expression should be linearized at the linearization point. Applicable only if evalmethod is harmonic.
evalmethod	linpoint \| harmonic \| lintotal \| lintotalavg \| lintotalrms \| lintotalpeak	harmonic	Applicable only for solutions with a stored linearization point. Controls if the linearization point, the perturbation, or a combination should be used when evaluating the expression.
expr	String	Model dependent	The expression to plot.
expressionintitle	on \| off	off	Whether the title contribution should contain the expression when titletype is custom.
nonlinearcolortablerev	on \| off	off	Whether to reverse to color table or gradient when coloring is set to colortable or gradient and colortabletrans is set to nonlinear or nonlinearsymmetric.
prefixintitle	String	Empty	Added prefix to contribution to title.
rangecoloractive	on \| off	off	Whether to use the manual color range specified in rangecolormin and rangecolormax. The color range specifies the minimum and maxim value in the plotted colors. Default is the minimum and maximum data values.
rangecolormax	double	Plot dependent	The maximum color range value. Active when rangecoloractive is on.
rangecolormin	double	Plot dependent	The minimum color range value. Active when rangecoloractive is on.
rangedatactive	on \| off	off	Whether to use the manual data range specified in rangedatamin and rangedatamax. Values outside the data range are not plotted.
rangedatamax	double	Plot dependent	The maximum data value. Active when rangedataactive is on.
rangedatamin	double	Plot dependent	The minimum data value. Active when rangedataactive is on.
suffixintitle	String	Empty	Added suffix to contribution to title.
title	String	The auto-title	The title to use when titletype is manual.
titletype	auto \| custom \| label \| manual \| none	auto	auto, if the title should be computed automatically. custom, if the title should be computed automatically, but customized. label, if the title should be the plot group’s label. manual, if the manual title should be used (the title property). none, if no title should be displayed.
typeintitle	on \| off	on	Whether the title contribution should contain the type when titletype is custom.
unit	String	Model dependent	The unit to use for the expression in expr. If the old unit is not valid when the expression changes, the unit property is reset to default.
unitintitle	on \| off	on	Whether the title contribution should contain the unit when titletype is custom.
