I am trying to plot multiple heatmaps using subplot
for i = 1:10
x(i).data = rand(10,10)
end
scale = 1:10;
p =1;
for j = 1:length(x)
subplot(5,2,p)
heatmap(scale(j)*x(i).data)
p =p+1;
end
In the output figure, the colorbar remains the same for all subplots even if the magnitude of values differ in each case.
For instance in subplot(5,2,1) values range from 0 to 1 and in subplot(5,2,2) values range from 0 to 2. However, I see the same color bar for both the subplots.
I'd like to know if there is a way to assign colors based on magnitude of values, something like a common colorscale for all subplots.

You can manually control the color limits of heatmaps:
h = heatmap(__,'ColorLimits',[0 10])
See HeatmapChart Properties.
