How to plot a polar plot with different colors or how to overlay the plots?

I have to have different colour for negative values and another one for positive values on the polar plot. The second option is to overlay two plots: one with negative and the other with positive values. My data is read from excel. I am adding a photo of a plot "Okres 3" to help you to see what it looks like. I would really apreciate your help. :)

Try something like this:

a = linspace(0, 2*pi);                                  % Create Data
r = sin(a) + cos(2*a);                                  % Create Data
ispos = r>0;                                            % Positive ‘r’ Values = ‘true’

figure
polarplot(a(ispos), r(ispos), '-r')
hold on
polarplot(a(~ispos), r(~ispos), '-g')
hold off
