How to keep the subplot sizes unchanged after putting a colorbar

matlab

Solution

You could just extract the position of the first plot and use on the second. MATLAB automatically moves the colorbar to the right when rescaling.

f1=figure(1);clf;
s1=subplot(1,2,1);
surf(peaks(20));

s2=subplot(1,2,2);
surf(peaks(20));
hb = colorbar('location','eastoutside');

%% # Solution:
s1Pos = get(s1,'position');
s2Pos = get(s2,'position');
s2Pos(3:4) = [s1Pos(3:4)];
set(s2,'position',s2Pos);



%% # Alternative method. Brute force placement
set(s1,'Units','normalized', 'position', [0.1 0.2 0.3 0.6]);
set(s2,'Units','normalized', 'position', [0.5 0.2 0.3 0.6]);
set(hb,'Units','normalized', 'position', [0.9 0.2 0.05 0.6]);

Problem

Let us say we have a 1-by-2 subplot and we plot some graphics inside as follows: ``` subplot(1,2,1) surf(peaks(20)) subplot(1,2,2) surf(peaks(20)) ``` And then we want to put a colorbar: ``` colorbar ``` I don't want the right figure squezzed as in the result. How can we put the colorbar out of the rightmost figure in a row of subplots and keep the sizes of them unchanged? Note: Actually, I need it for plotting images where the colorbar is common and I want to put it on the right. I used this toy example for simplicity.
