Yes, that's the same sort of graphic I'm getting.

But there is no residue 45!  So there should be no number 45 anywhere on 
the picture.

I think the problem is that the tick strip is displaying numbers for the 
ticks instead of the intervals. The intervals are what corresponds to 
users' models of physical reality and my graphics need to match that.

I guess I'll have to experiment and patch until it does what I want 
then, if nobody knows how to do it.
