I want to set the min and max range of colormap
I want to set the limits of colormap based on the mix and max of values stored in data
data = rand(10,10);
min = min(min(data))
max= max(max(data))
Any suggestions on how this can be done?

caxis([min(data(:)), max(data(:))]);

That's because you clear your figure with clf right at the start of the loop! That clears everything including what you set up with caxis(). Don't call clf.
