Re: [Visualpython-users] Changing a graph

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

Perhaps this is what you're looking for:

from visual import *
from visual.graph import *
# From the VPython Help:
#    If you say g = gcurve(), g.gcurve is
#    a curve object used to represent the gcurve.
#    Every gdisplay has the attribute "display".
d = gdisplay()
g = gcurve()
g.plot(pos=(2,1))
g.plot(pos=(5,3))
d.display.mouse.getclick()
g.gcurve.pos = [(1,3), (4,1)]
