Brian Douglas 107,323 views. The values can be an array of angles or array of magnitude. polarpattern class plots antenna or array radiation patterns in interactive polar format. Right-click the Polar Measurement window to change the properties, zoom in, or add more data to the plot. Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB ® uses in many types of plots. We can change the limits of the angle axis by using the thetalim function in Matlab. polar(theta,rho,LineSpec) LineSpec specifies the line type, plot symbol, and color for the lines drawn in the polar plot. For more information on legend label format see, legend. Hi guys, when plotting a polar plot I find that the program does not join the first and last points plotted around the compass.
