I'm not completely sure if this is what you're looking for, but maybe this example helps:Hello,I want to plot the data inside a matrix, but with different colors for the negative and positve terms. I do this now by spliting the matrix into two (negative, positive) using a "for" loop, and I wonder if there is another better approach to do this.Any hint welcome :) Regards, Alvaro.
