Is this what you had in mind?
xedge = 2.1:.1:3;
freq = [43 41 31 29 13 9 3 2 1];
bar(xedge, [freq 0], 'histc')

Here is the orignal data set. I have created the ranges lets say 2.1-2.199 and counted numbers in series above 2.1 adn next 2.2-2.299 and again counted numbers above 2.2 and so on to get frequency
