Hello ,

I'm trying to change the colormap on my heatmap, I'm using right now the '"money" color but I'm want to be blue one, I tried many options without any luck. Any help will be appreciate.

Thanks.

Here is a helpful resource for this question. You can make and save any colormap you want throught the colormap editor:

Change the Colormap property of the heatmap, either when you construct the heatmap:

h = heatmap(magic(5), 'Colormap', copper);

or afterwards.

h.Colormap = flag;

If none of the predefined colormaps are suitable for your application you can build your own as an M-by-3 matrix, either manually or using the colormapeditor as per Jessica Lovering's comment.

h.Colormap = repmat(linspace(0, 1, 25).', 1, 3);

You can also use the colormap function:

figure

heatmap(magic(5))

colormap(parula)

or

figure

h = heatmap(magic(5))

h =

HeatmapChart with properties: XData: {5×1 cell} YData: {5×1 cell} ColorData: [5×5 double] Show all properties

colormap(h, parula)

There's also a new colormap named sky introduced in release R2023a that may be of interest if you want a colormap from white or very light blue through dark blue.

heatmap(magic(4))

colormap(sky)
