I would like to add information about min, max, mean, median, and st dev to the histogram. I tried to do this using the following script:
% Import data
A = importdata('C:\my_data.tif');
% Generate histogram
histogram(A,'BinLimits',[0,1000]);
% Calculate the min, max, mean, median, and standard deviation
min=min(A);
max=max(A);
mn=mean(A);
md=median(A);
stdv=std(A);
% Create the labels
minlabel=sprintf('Min -- %3.2d', min);
maxlabel=sprintf('Max -- %3.2d', max);
mnlabel=sprintf('Mean -- %3.2d', mn);
mdlabel=sprintf('Median -- %3.2d', md);
stdlabel=sprintf('Std Deviation -- %3.2d', stdv);
% Create the textbox
h=annotation('textbox',[0.58 0.75 0.1 0.1]);
set(h,'String',{minlabel, maxlabel,mnlabel, mdlabel, stdlabel});
However, every time when I run the script the last line of the script crushed in Matlab (see attached message). Does anyone know how to solve the error? Or is there another way to add min, max info to the histogram? Thanks in advance for the answer.

I'd contact tech support if the crash is reproducible.
A minimal working example works for me:
histogram(rand(100,1))
annotation('textbox','String',{'hello', 'world'})

Thank you for the answer. Yes, the error, unfortunately, occurs every time.
Your script works well, but I have to generate a lot of histograms, so I would like to have the possibility to add the min, max, mean, median, stdv values automatically instead of typing them every time manually. Is there a way to do this?

What you have above should work. In fact, if I copy it and run it with a synthetic A matrix, it does. So it probably has something to do with your A matrix. What does your A matrix look like (size, are there nan/inf values, class etc.)?

Thank you for your answer and for verification of the code. So the problem is probably with: matlab or my data.
Below you can find the properties od my data.
I tried also to use the code dor different data but the Matlab also crushed

Contact tech support! It could quite possible by a simple graphics driver update or something specific to your machine that they can help with!
