How can I color an angle histogram created by the ROSE function in MATLAB?

4 views (last 30 days)
I use the ROSE function to create an angle histogram:
theta = 2*pi*rand(1,50);
rose(theta);
In the resulting plot, the angled bars are not colored. I would like to fill the histogram with a certain color.

You can use the FILL command to color the angle histogram. The following example the fill color is red:
theta = 2*pi*rand(1,50);
[tout, rout] = rose(theta);
polar(tout, rout);
[xout, yout] = pol2cart(tout, rout);
set(gca, 'nextplot', 'add');
fill(xout, yout, 'r');
You can substitute any colorspec or color triplet for 'r'.
