Hi,

I was looking for a way to change the colormap for histogram2 from parula to something else. Couldn't find it.

x = randn(5000);
y = randn(5000);
h = histogram2(test1, test2, 'DisplayStyle','tile');

again: I couldn't find any handle or option to change the colormap.I'd appreciate a hint.

kind regards

Arnold

Use the colormap function. First let's make the histogram2 plot.

x = randn(5000);
y = randn(5000);
h = histogram2(x, y, 'DisplayStyle','tile');

Next, I'll enable the colorbar (so we can see the color scale.)

Finally I'll change the colormap. I'll use jet but you can use one of the ones on the colormap documentation page or one of your own design.
