How to generate polat plot for 4 variables

2 views (last 30 days)
I would like to generate polar scatter plot for 4 variables (aspect, elevation, slope, area), where:
aspect - represent angular axis
elevation - represent radial axis (the distance from the center)
slope - represent the color of plot (grading color)
area - represent the size of dots
After typing the code (attached below) in Matlab R2014b I have the following error: Undefined function 'polarscatter' for input arguments of type 'double'. Does anybody know what can be wrong?
clear; clc; close;
D = [500.0 450.0 600.0 350.0]; % Elevation
S = [5.0 40.0 25.0 15.0]; % Slope
AS = [25.0 225.0 15.0 60.0]; % Aspect
A = [100.0 55.0 70.0 20.0]; % Area

You need R2016b for polarscatter().

You can use scatter(). It should not be that difficult to transform polar coordinates to cartesian coordinates. Matlab even has cart2pol() and pol2cart() to help you.
