Well, I'm not David, but you need to set the levels appropriately. This line:

levels = Indgen(16)*100

produces levels of 0, 100, ..., 1500. You should change that to something more appropriate for your data.

And, if you change the number of levels (here, 16) you'll need to change a few things in the rest of the code too.
