imhist & suppress color bar

Quick question: I am trying to overlay 2+ image histograms, using imhist (as it provides the color bar at the bottom). When I try to make more than one, using hold on, it adds extra color bars to the bottom. Is there a way to supress that output (or is there a better option I am unaware of)? Idealy the output should look like the output of the code below but with only 1 color bar.

Quick example of what's happening:

I = imread('moon.tif');
I1 = I(100:120,210:230);
I2 = I(450:470,170:190);
I3 = I(370:390,60:80);

figure
hold on
imhist(I1);
imhist(I2);
imhist(I3);
hold off

Try this

I = imread('moon.tif');
I1 = I(100:120,210:230);
I2 = I(450:470,170:190);
I3 = I(370:390,60:80);

f = figure;
ax = axes();
hold on
imhist(I1);
pos = ax.Position; % save the axes position because next commands will resize it
imhist(I2);
imhist(I3);
hold off

stripes = findall(f, 'Tag', 'colorstripe');
delete(stripes(1:end-1))
ax.Position = pos;
