Hi Ted, 

I hadn't thought of using a stack.  What is the argument for a stack
as opposed to a single state manipulated along the lines of (with try
except as needed)

 b = isinteractive()
 ioff()
 ....your plot here...
 if b: ion()

Your approach requires one fewer line of code.  Are their other
advantages to a stack approach?  I think a stack may be slightly less
intuitive to a typical user, whereas turning drawing mode on and off
is fairly straight forward.
