One area is plotting data in a polar plot. For all circuit objects except those that contain data from a data file, you must use the analyze method to perform a frequency domain analysis before calling polar.. Use the function polarpattern (Antenna Toolbox), or the MATLAB ® function polarplot to plot parameters that are not part of a rfckt or rfbudget object, but are specified as vector data. Thus, the color codes Therefore I end up with a noticable gap between the two if the values are significantly different. For a list of polar (theta,rho) creates a polar coordinate plot of the angle theta versus the radius rho. To convert data from degrees to radians, use deg2rad. of a specific chart line object after it is created. PolarAxes object. Alternatively, one of the inputs can be a vector and the other a matrix For a list of properties, see PolarAxes Properties. '#ff8800', If it is in degree, then we should convert it into radians by using deg2rad function in Matlab and use it in the plot.
