ImpulseResponse
Create an impulse response plot for 1D plot groups. This plot type requires the Acoustics Module.
Syntax
model.result(<pgtag>).create(<ftag>,"ImpulseResponse");
model.result(<pgtag>).feature(<ftag>).set(property, <value>);
model.result(<pgtag>).feature(<ftag>).run();
Description
model.result(<pgtag>).create(<ftag>,"ImpulseResponse") creates an impulse response plot feature named <ftag> belonging to the plot group <pgtag>.
Impulse response plots are primarily used for postprocessing of acoustics simulations. Impulse response plots can be added to 1D plot groups.
The following properties are available:

linewidth
double
0.5
The line width.

none
The line markers, if any. Cycle indicates that the marker is different for each line.
linestyle
none | cycle | solid | dotted | dashed | dashdot
solid
The line style, if any. Cycle indicates that the line style is different for each line.
markerpos
interp | datapoints
interp
Controls whether the positions of the markers are in the data points of the plot, or interpolated depending on the number (set in markers). Markers are visible when linemarker is set.
markers
integer
8
The number of markers to show. Markers are visible when linemarker is set.
nfreqs
integer
1
If transform is spectrum and nfreqsactive is true: The number of frequencies to plot.
nfreqsactive

scale
Boolean
false
If transform is spectrum: The frequency spectrum is transformed so that it has the same scale as the original data.
solnum
nonnegative integer array
All solutions
The solutions to plot. Available when data is not parent and the underlying data has multiple solutions.
solnumindices
String or integer array
Empty
An alternative way to specify the solutions to use, allowing you to enter, for example, range(1,1,20). Applicable when innerinput is manualindices.
solrepresentation
