[Visualpython-users] Plotting Issues

Hello all,

I'm having trouble seeing plots in VPython. When I run graphtest.py I can
only see the red histogram and the yellow dots, but not the cyan curve. This
behavior also shows up when I create a plot of my own, except I can't see
any curves at all. The graph window appears and the axes scale as though
data is being plotted, but it is invisible.

Any help/suggestions/guidance would be appreciated.
