OctaveBand
Create an Octave Band Plot.
The Octave Band Plot requires a license for the Acoustics Module, MEMS Module, or Structural Mechanics Module.
Syntax
model.result(<pgtag>).create(<ftag>,"OctaveBand");
model.result(<pgtag>).feature(<ftag>).set(property,<value>);
model.result(<pgtag>).feature(<ftag>).run();
Description
model.result(<pgtag>).create(<ftag>,"OctaveBand") creates an octave band plot feature named <ftag> belonging to the 1D plot group <pgtag>.
The octave band plots a weighted frequency response in bands (octave or 1/3 octave) or as a continuous frequency response. The frequency can be weighted.
The following properties are available:
