COMSOL 6.2 - Point

Create a point plot in 2D or 3D.

model.result(<pgtag>).create(<ftag>,"Point");

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

model.result(<pgtag>).feature(<ftag>).run();

model.result(<pgtag>).create(<ftag>,"Point") creates a point plot feature named <ftag> belonging to the 2D or 3D plot group <pgtag>.

Point plots are used to visualize points using different geometric shapes and to plot torque arrows in 2D. Point plots can be added to 2D and 3D plot groups.

The following properties are available:

Table 7-111: Valid Properties for Point Plots.
name	Value	Default	Description
bottomcolor	custom \| black \| blue \| cyan \| gray \| green \| magenta \| red \| white \| yellow	black	The bottom color to use for a color gradient. Active when coloring is gradient.
color	custom \| black \| blue \| cyan \| gray \| green \| magenta \| red \| white \| yellow	red	The uniform color to use. Active when coloring is uniform.
coloring	colortable \| uniform \| gradient	colortable	How to color the points: using a color table, a uniform color, or a color gradient.
colorlegend	on \| off	on	Whether to show color legend when coloring is set to colortable.
colorscalemode	linear \| linearsymmetric \| logarithmic	linear	Scaling of the color table: linear, linear symmetric around 0, or logarithmic, when coloring is set to colortable or gradient.
colortable	color table name	Rainbow	The color table to use when coloring is set to colortable. See Color Tables for a list of color tables.
colortabletrans	none \| reverse \| nonlinear \| nonlinearsymmetric	none	Transformation of the color table, when coloring is set to colortable or gradient.
custombottomcolor	RGB-triplet	{1,0,0} or last used color	The uniform color to use. Active when bottomcolor is set to custom.
customcolor	RGB-triplet	{1,0,0} or last used color	The uniform color to use. Active when color is set to custom.
customtopcolor	RGB-triplet	{1,0,0} or last used color	The uniform color to use. Active when topcolor is set to custom.
data	none \| parent \| dataset name	parent	The dataset this feature refers to.
expr	String	Model dependent	The expression to plot.
fixedpointsize	true \| false	false	Whether to use a fixed point size.
heightexpr	String	1	Height expression, if pointtype is rectangle or ellipse.
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.
pointtype	point \| block (3D) \| ellipsoid (3D) \| torque (2D) \| rectangle (2D) \| ellipse (2D)	point	The point type: point, block, or ellipsoid in 3D; point, torque, rectangle, or ellipse in 2D.
radiusexpr	String	1	Point radius expression, if pointtype is point or torque.
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.
rotexpr	String	0	Rotation expression, if pointtype is rectangle or ellipse.
sphereradiusscale	positive double	1	The scale factor applied to the point radii.
solutionparams	manual \| parent	manual	If data is a local dataset with nontrivial data, specify solutions manually or take them from the parent plot group.
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.
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.
transformexpr	3-by-3 array	{"1","0","0";"0","1","0"; "0", "0", "1"}	The three axis vectors determining the size and rotation for 3D points with pointtype set to block or ellipsoid. Specify them using the setIndex method.
widthexpr	String	1	Width expression, if pointtype is rectangle or ellipse.
