Heatmap charts use the 256-sampling of the sky colormap by default. You can change the colormap and the sampling by specifying the Colormap name-value argument of the heatmap function.

For example, create two heatmap charts in a 2-by-1 tiled chart layout. The top chart uses 256 colors of the abyss colormap, and the bottom chart uses only two colors.

tiledlayout(2,1)

% Top chart with default number of colors
nexttile
cdata = magic(10);
heatmap(cdata,Colormap=abyss)
title("256 Colors")

% Bottom chart with two colors
nexttile
heatmap(cdata,Colormap=abyss(2))
title("2 Colors")

Figure contains objects of type heatmap. The chart of type heatmap has title 256 Colors. The chart of type heatmap has title 2 Colors.
