gdots not working

[W. Brian Lane]

I have encountered a problem with using gdots. When using a code such as 

from visual.graph import *

mygraph = gdots(color=color.red)

mygraph.plot(pos=(1,1))

mygraph.plot(pos=(0,0))

my resulting graph shows only a single data point, which is not at any of the specified positions:

I have uninstalled and reinstalled python 2.7.9 and VPython-Win-32-Py2.7-6.11. gcurve, on the other hand, is working fine. For example,

from visual.graph import *

mygraph = gcurve(color=color.red)

mygraph.plot(pos=(1,1))

mygraph.plot(pos=(0,0))

produces (correctly)

Any suggestions?

I have no idea how gcurve can work and gdots fail. Your program works for me. I'm running 64-bit Windows, but I wouldn't expect a difference between 32-bit and 64-bit. Are you able to try the 64-bit version? Or either the newer GlowScript VPython or Jupyter VPython?

Note that site-packages/visual_common/visual_common/graph.py contains the graphing code, written in Python, so you could put in some print statements in the gdots class and perhaps get more information that way.
