Color
Add a color expression attribute to add a coloring to the shapes defined by a plot.
Syntax
model.result(<pgtag>).feature(<ftag>).create(<atag>,"Color");
model.result(<pgtag>).feature(<ftag>).feature(<atag>).set(property, <value>);
Description
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 plots.
The following properties are available:

descr
String
Model-dependent.
The description of the expression in expr. Is used in the automatic title.

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.

on | off
off
Whether the title contribution should contain the expression when titletype is custom.
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.
Color Tables
The following color tables are available for use with the colortable property here and in other types of plots: AuroraAustralis, AuroraAustralisDark, AuroraBorealis, Cividis, Cyclic, Disco, DiscoLight, GrayPrint, GrayScale, HeatCamera, HeatCameraLight, JupiterAuroraBorealis, Rainbow, RainbowLight, Spectrum, Thermal, ThermalEquidistant, ThermalLight, ThermalNarrow, Traffic, TrafficLight, Twilight, Wave, and WaveLight.
