Directivity
Create a directivity plot. A directivity plot is an extension of far-field plots and is a common acoustic plot for speakers. This plot collects spatial information across frequencies and shows this data as a contour plot.
Directivity plots are available with the Acoustics Module.
Syntax
model.result(<pgtag>).create(<ftag>,"Directivity");
model.result(<pgtag>).feature(<ftag>).set(property, <value>);
model.result(<pgtag>).feature(<ftag>).run();
Description
model.result(<pgtag>).create(<ftag>,"Directivity") creates a directivity plot feature named <ftag> belonging to the plot group <pgtag>. Directivity plots are available in 2D plot groups.
The following properties are available: 
manual | none
custom | black | blue | cyan | gray | green |magenta | red | white | yellow
colortable | uniform
on | off
The color table to use when coloring is set to colortable. See Color Tables for a list of color tables.
on | off
Whether to reverse to color table when coloring is set to colortable.
on | off
on | off
lines | filled
{1,0,0} or last used color.
{1,0,0} or last used color.
none | parent | data set name
The description of the expression in expr. Is used in the automatic title.
on | off
on | off
linpoint | harmonic | lintotal | lintotalavg | lintotalrms | lintotalpeak
on | off

logarithmic | linear
on | off
If inheritplot is not none: Determines if the color is inherited.
none | plot name
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.
frequencyx | frequencyy
number | levels
custom | black | blue | cyan | gray | green | magenta | red | white | yellow
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.
angle | max | none
If anglerestr is manual: The minimum phi angle in degrees.
If anglerestr is manual: The phi angle’s range in degrees.
off | pprint | ppr
{0, 0, 1}
The element refinement to use, if resolution is set to manual. Bear in mind that this is the refinement used for the base data set, so the number of elements in the model can increase radically if the plot uses, for example, a revolve data set.
norefine | coarse | normal | fine | finer | extrafine | custom
The index of the solution to use. Available when data is not parent and the underlying data has multiple solutions.
solnum | solutioninfo
The time to use, for transient problems. Available when data is not parent and the underlying data is transient.
manual | none
Threshold value (0-1), if threshold is set to manual.
on | off
on if t is used to determine time steps, off if solnum is used.
The title to use when titletype is manual.
auto | custom | manual | none
auto if the title contribution should be computed automatically, possibly using the group’s customization. custom if the title contribution should be computed automatically, but customized. manual if the manual title contribution should be used (the title property). none if no title contribution should be used.
on | off
The unit to use for the expression in expr. If the old unit is not valid when the expression changes, the unit property is reset to default.
on | off
