Issue with "autorange_after_scroll" when using an arbitrary function

[rjgrandy]

The "autorange_after_scroll" function does not seem to work correctly when I use an arbitrary function to define different X and Y values (put new values into xs and ys. It scales the largest Y axis to the largest Y value in the data.

If I only change the return xs and ys to return the orginal xs and ys and nothing else, it seems to work fine. So maybe there is something wrong with the data I am passing, but it seems to display fine and I can't see a difference when I debug.
