How to make 3 bar subplots have the same scale?

I have a plot with 3 subplot of barplots. How do I set the same axis range for all three of them?

Answer 1

Use the output from subplot to store the axes. Then set the XLim and YLim of the axes.

figure
ax = zeros(3,1);
ax(1) = subplot(3,1,1);
bar(1:10,3*rand(1,10))
ax(2) = subplot(3,1,2);
bar(1:20,2*rand(1,20))
ax(3) = subplot(3,1,3);
bar(1:30,rand(1,30))

set(ax,'XLim',[-5 35],'YLim',[-2 5],'XTickMode','auto','YTickMode','auto');
