I want to add a histogram to a GUI, but i have to keep it small, when i initiate it, it shows a value of 5000 on y axis whereas the frequency of pixels is less than 500 so i want to decrease it to clearly show the bars. So can anybody tell me on how to change y axis limit in imhist.

Take the log before you display it. Or suppress one of the bins by setting it to zero. You can change the limits with ylim
ylim([0 500]);

i declared my y axis to be R_size but when i use the above command the matlab pops error as " Undefined function or variable 'R_sizelim'"
It would be easier to get an answer by asking a new question, instead of commenting on a two-year old post.
Seems like you might want something like:
R_size.YLim = [minim, maxim]
