I have a correlation coefficients matrix consisting of positive and negative values and I need to plot the graph for that matrix separating positive and negative values with different colors to distinguish them.

Hi, I checked the code but that doesn't work for me.My matrix is 11*11.

Ok, so what you can do is that you can create two separate linear arrays of positive and negative numbers from the matrix and then plot each array with different color.
