[Plplot-general] Zooming in??

[S V. <sve...@ho...>]

Hello,
I am working on extending the wxPlot binding to PLPlot in order to make a 
general plotting widget usable in wxwidgets. After some work I got the 
freetype support and resizing to work smoothly (no flicker etc.)
However, I cannot figure out how to use the zooming functionality. According 
to the documentation I came up with plsdiplz and/or plsdiplt. But how should 
those functions be used? For example executing diplz(.2,.8,.2,.8)  followed 
by a replot() gives me an empty screen and I cannot find an examplle that 
does something like that (zoom in on a selected region of the current plot).

Any help or tip is greatly appreciated!
