MATLAB: How to change the properties of “patternElevation” or “patternAzimuth” polarpattern plots

Question

How to change the properties of "patternElevation" or "patternAzimuth" polarpattern plots used for plotting Elevation/Azimuth pattern of antenna or array? 

Answer 1

In this case "patternElevation" or "patternAzimuth" function plots are of "polar pattern" types plots. You can grab the handle for these plots using the following command: 

>> pAx = polarpattern('gco'); % grab the handle for current polar plot

Please take a look at the different commands that you can use to manipulate different properties: 

1. How to change line specification in the "patternElevation" plot?  *

>> d = dipole; % Create dipole

>> patternElevation(d,70e6,[0 45],'Elevation',-140:5:140); % Plot the figure using "patternElevation" function.

>> pAx = polarpattern('gco'); % grab the handle for polar plot

• Please see the following documentation page for changing the 'LineStyle' property. 
• https://www.mathworks.com/help/antenna/ref/polarpattern-properties.html#property_d119e64337

2. How to change the magnitude limits using script? 

• Use the pAx handle created in step 1, to change the "MagnitudeLim" property. Please the see the link below to manipulate the value for this property. 
• https://www.mathworks.com/help/antenna/ref/polarpattern-properties.html#property_d119e61997

>> pAx.MagnitudeLim % Shows current value for "MagnitudeLim" property.

3. Peaks in the plot are shown only for one dataset at a time. Is there any way to visualize peaks table for multiple data sets? 

• You can get all the "PeakMarkers" property values in the script. But currently there is no way to show both data set peak values in one table. You can switch between data set by clicking on lines in the plot to change the displayed values in "Peaks" table in this plot.

>> pAx.PeakMarkers % Returns 2 X1 struct array with "magnitude" field which contains the peak values
