So I am going to assume you are using a loop, and lastLabel is a variable set to the last label created in the loop. You're code's going to break on the first iteration since it can't divide a null value by 2. You need to either set an initial value for lastLabel before the loop or not process that line on the first iteration, instead setting the position. That is probably what you really want to do since you would want your first label to be at a fixed position and the second to base it off of that.
I hope it doesn't seem that I'm talking down to you, I'm just trying to determine the best I can out of the little bit I'm seeing here. --- In [email protected], Richard Rodseth <rrods...@...> wrote: > > Yes, I know a null pointer exception is not charting-specific :) > > None of my code is in the stack crawl (shown below).
