MatrixHistogram
Create a matrix histogram plot for 2D plot groups.
Syntax
model.result(<pgtag>).create(<ftag>,"MatrixHistogram");
model.result(<pgtag>).feature(<ftag>).set(property, <value>);
model.result(<pgtag>).feature(<ftag>).run();
Description
model.result(<pgtag>).create(<ftag>,"MatrixHistogram") creates a histogram plot feature named <ftag> belonging to the plot group <pgtag>.
Use a matrix histogram if you have a precomputed matrix that you want to visualize as a 2D histogram. For example, in a fatigue analysis, you can use it for rainflow counting to visualize the distribution of stress amplitudes and mean stresses. The matrix then contains data points in the xy-plane, where the x- and y-values are stresses. Matrix histogram plots can be added to 2D plot groups.
The following properties are available:
