Re: [Visualpython-users] Getting a simple graph animation plot to show

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

Thanks, Lenore, for answering John's question. A further simplification is that in the plot statement there's no need to specify "gdisplay=Xvel.display" because Xvelnodrag was created for and belongs to that gdisplay.

Xvel = gdisplay(x=0,y=0, width=262, height=100,  
background=color.white, xmin=0, xmax=12, ymin=-vmax, ymax=vmax, title  
= 'V_x(t)')
Xvelnodrag = gdots(size=3, color=nodragcolor)
......
  Xvelnodrag.plot( gdisplay=Xvel.display, pos=(t,nodrag.velocity.x) )

John, if you're comfortable with the default gdisplay and gdisplay settings the minimal structure for making a graph is something like this:

Xvelnodrag = gdots() # create a gdots object for graphics

...........
  Xvelnodrag.plot(pos=t,nodrag.velocity.x)) # add a dot to the gdots object
