Re: [Visualpython-users] xmin in gcurve object

[Bruce S. <Bru...@nc...>]

The current version (5.71) of VPython lets you do exactly what you are
requesting. Here's the new paragraph from the documentation:

Offsets: If you specify xmin or ymin to be greater than zero, or xmax
or ymax to be less than zero, the crossing point (origin) of the x and
y axes will no longer be at (0,0), and the graphing will be offset. If
you offset the origin of the graph, you must specify xmax to be
greater than xmin, and/or ymax to be greater than ymin.
