Contour
Create a contour plot.
Syntax
model.result(<pgtag>).create(<ftag>,"Contour");
model.result(<pgtag>).feature(<ftag>).set(property, <value>);
model.result(<pgtag>).feature(<ftag>).run();
Description
 model.result(<pgtag>).create(<ftag>,"Contour") creates a contour plot feature named <ftag> belonging to the plot group <pgtag>. Contour plots are available in 2D and 3D plot groups. Contour lines are colored by their level. Add a color expression attribute to color them by an arbitrary expression.
The following properties are available:

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.
includeoutside
on | off
on
Fill surfaces outside of contour levels if contourtype is filled.
inheritcolor
Boolean
true
If inheritplot is not none: Determines if the color is inherited.
inheritdeformscale
Boolean
true
If inheritplot is not none: Determines if the deformation scale is inherited.
inheritplot
none | plot name
none
The plot that color and deformation scale are inherited from.
interp
double array
Time corresponding to last selected solnum for transient levels.
The time to use, for transient levels. Available when data is not parent and the underlying data is transient.
levelmethod
number | levels
number
How to specify contour levels.
labelcolor
custom | fromtheme | black | blue | cyan | gray | green | magenta | red | white | yellow
fromtheme
If contourlabels is on: The label color to use. The default value uses a color from the color theme.
labelprec
positive
integer
If contourlabels is on: The number of significant digits in the labels.
legendtype
auto | filled | lines
auto
Whether to show the color legend as a filled legend or using lines. The auto setting provides a filled legend for filled contours and a line legend for line and tube contours.
levelrounding
Boolean
true
Round the contour level values, if levelmethod is set to number.
levels
String array
 
The specific levels to plot. Active when levelmethod equals levels.
looplevel
array of nonnegative integers and strings
Last solution for transient or parametric solution for each level. Otherwise, first solution for each level.
The index of the solution to use, per level, or interp, but only for transient solutions. Available when data is not parent and the underlying data has multiple solutions.

positive integer

String
Empty
Added prefix to contribution to title.

String
1

recover
off | pprint | ppr
off
The derivative recovery method (off, within domains, or everywhere).
refine
nonnegative integer
1
The element refinement to use, if resolution is set to manual. Bear in mind that this is the refinement used for the base dataset, so the number of elements in the model can increase radically if the plot uses, for example, a revolve dataset.
resolution
norefine | coarse | normal | fine | finer | extrafine | custom
normal
Controls the plot’s resolution. A finer setting results in a higher resolution by modifying the internally computed default refinement. Use custom to enter your own refinement in the refine property.
smooth
none | material | internal | everywhere | expression
material
Smoothing settings. With material, smoothing is done inside domains with the same material. With internal, smoothing is done inside geometry domains. With expression, the smoothing is based on the expression in smoothexpr.

String
dom
The expression to use for smoothing when smooth is set to expression.
solnum
nonnegative integer
Last solution for transient or parametric solution. Otherwise, first solution.
The index of the solution to use. Available when data is not parent and the underlying data has multiple solutions.
solrepresentation
solnum | solutioninfo
solutioninfo
Indicates which method of selecting solutions is active.
solutionparams
manual | parent
manual
If data is a local dataset with nontrivial data, specify solutions manually or take them from the parent plot group.
suffixintitle
String
Empty
Added suffix to contribution to title.
t
double
Time corresponding to last selected solnum.
The time to use, for transient problems. Available when data is not parent and the underlying data is transient.

Use a smoothing threshold.
thresholdvalue
double
0.1

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.
topcolor
custom | black | blue | cyan | gray | green | magenta | red | white | yellow
white
The top color to use for a color gradient. Active when coloring is gradient.
tuberadiusscale
double

The scale factor for the tube radius when the contour type is set to tubes.

typeintitle
on | off
on
Whether the title contribution should contain the type when titletype is custom.
