Hi, I have a 100x100 matrix where the entries are either >4 (no greater than 6) or less than 4.

I want to plot this matrix using imagesc and make it so that the pixels whose corresponding entries <4 are colored blue, and the pixels whose corresponding entries >=4 are colored red.

As background info, I'm trying to simulate an abelian sandpile and want to show how criticality builds.

colormap([0 0 1;1 0 0]);
imagesc(TheImage>=4);
