[Visualpython-users] W hen you create a gcurve, gdots, gvbars, or ghbars object, you can provide a list of points to be plotted, ....

[Jon S. <js...@gm...>]

The documentations seems to be self-contradictory (can a list be used for
all the g* objects or just the gdots object)?


When you create a gcurve, gdots, gvbars, or ghbars object, you can provide a
list of points to be plotted, just as is the case with the ordinary curve
 object:
values = [(1,2), (3,4), (-5,2), (-5,-3)]
data = gdots(pos=values, color=color.blue)
*This list option is available only when creating the **gdots** object.*


I find it works with gdots but not with gcurve....

Thanks for catching this! Yes, the documentation is indeed self-contradictory; 
only gdots accepts a list of points, but they all should; this is an oversight. 
It involves I think a pretty simple fix to graph.py -- just emulate for the 
other objects what's done for gdots.
