How to save histogram as a png file with the axis values (as it displays in imhist() function ) inside a loop?

Hello, I am new to matlab, I want to save the histogram as it shows in the imhist function. but when I save it, it only saves the spikes (bars), but, does not save the entire histogram (x and y axis are not saved with with the spikes). also I want to create a histogram in each irritation of the loop and save them with different name, (as Hist11, Hist12, hist21,hist22.....etc) the name will contain the row number and column number. Here is the code I have tried already. Thank You.

       imwrite(imhist(temp),'F:\499\Histogram\h1.png');
       saveas(im1,sprintf('HIS%d.png',i));

Try:

imhist(temp);
saveas(gcf,sprintf('HIS%d.png',i));

Hi,

You can save the entire histogram using as it shows in the imhist functions using the below code snippet.

saveas(gcf,sprintf('HIS%d.png',i))

Run this snippet in the loop to create multiple histograms and save them.

I am giving an example code with loop to create and save multiple histograms.

x=[1 2 2 4 4 5 5 5];
while(length(x)<15)
imhist(x)
saveas(gcf,sprintf('HIS%d.png',length(x)))
x=[x length(x)];
end

Thank you.
