Can't figure out why short figure won't work

[Sorry I can't quote past messages as I get mail on Nabble and have been 
told I can't reply through Nabble].

Thanks Kennel for recommended a narrowing range for usr y-limits.  That 
does help quite a bit.

But I found a disappointing aspect of the graphics system: When you 
change height= on the device call you have to change the y-coordinates 
to keep the same absolute vertical positioning.
