Properly scale histogram in subplot and error handling

Hey there,

when I am trying to subplot an image and its histogram the histogram is stretched too far in vertical space. I am also getting the following error code:

% Error using imageDisplayValidateParams
% Expected input number 1, I, to be one of these types:
% numeric, logical
% Instead its type was matlab.graphics.chart.primitive.Histogram.

The code I am using is the following and this should be reproduceable with any image I think:

IMG  = imread('img.tif');
subplot(1,2,1); imshow(IMG);
subplot(1,2,2); imshow(histogram(IMG));

Does someone know how to fix this error and how to properly resize the histogram?

Thank you in advance!

Thank you very much, this for startes solves the error that occured.

Is there any way to resize the histogram? When plotted next to each other the histogram is stretched verticaly and it looks kind of odd.

IMG  = imread('img.tif');
subplot(2,1,1); imshow(IMG);
subplot(2,1,2); histogram(IMG);

The axes autosize according to the figure width. You can click and drag the figure edge to resize it until the histogram size matches the image size.
