My task is to acquire the frequency values of the H and S values of an image. Therefore, I'm trying to generate a HS histogram of an image. However, I looked up numerous sources and they all create the H and S histograms separately. To state my problem more clearly, how do I know the number of time the H and S values occur together as a pair? Can anyone point me to the right direction?
Thanks!

Adjust the scale factor and add 1. See my edited comment above.

Thanks! I took the liberty of putting an if statement that would make the 0 values into 1 instead. Then I used a surf plot to see the result.
