Hello,
I am trying to create a histogram where each bin is the length of the increments in another vector. Can anyone explain what I'm doing wrong with:
histc(screenhit,x)
where screenhit is the vector I want a histogram of, and x is simply a vector of numbers in increments of 0.01.
Thanks.

What result did you get? What result did you expect? It would be much more efficient to answer your question knowing that. If you want a plot with histc, you need it to do it yourself. Read the documentation, there's an example there.

I was getting a histogram when I used hist instead of histc. But as I understood it, it is easiest to set the size of each bin using histc. Unfortunately it returns nothing at all.

Well, nothing you've showed us looks suspicious, nor does it allow us to reproduce the problem.

Try this:
screenhit = randi(50, 1000, 1);
x = sort(50*rand(50,1)); % 50 random edges of bins
counts = histc(screenhit,x)
bar(counts, 'BarWidth', 1);
It certainly returns something!
