Right. I didn't mention that.

Another simple minded approach I thought of was making some IDLgrPolygon objects
that sit around the plot limits. This way, any lines that were plotted beyond the
axis would be hidden by the polygons. There would be alot of extra rendering
happening of course. Despite the inelegance, the advantage would be that you
wouldn't have to change the ranges of the plots.

P.S. This illustrates one reason why I wish there was a way to call methods on an
object array without looping: when you are setting a property of all the objects to
the same value.
( PlotObjArr->SetProperty, xrange=xr,yrange=yr )
