How can I properly create histogram of DICOM image?

29 views (last 30 days)
Dear all,
I have DICOM image and I would like to create histogram of it. But I created only this:
grayImage = dicomread('000054.dcm');
figure()
imhist(grayImage);
[X,map] = imread('trees.tif');
grid on;
title('Histogram testovacího obrazu');
caption = sprintf('Histogram testovacího obrazu %s');
title(caption, 'FontSize',fontSize, 'Interpreter', 'None');
ylabel('Četnost');
I attach this DICOM image. But I would like to better displayed this histogram (different range of x axe).
Can you advice me? Thank you for your answers.

What is the intention of the line
[X,map] = imread('trees.tif');
?
