Re: [Visualpython-users] movement in 3D and visibility in gdisplay

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

Here is an example:

from visual.graph import *

g = gdisplay()
c = gcurve(color=color.cyan)
c.plot(pos=(1,0))
c.plot(pos=(2,1))
print c.gcurve.pos # undocumented gcurve attribute; c.gcurve is a curve object
for y in arange(1,0.1,-.01):
    rate(40)
    c.gcurve.pos[1] = (2,y,0)
g.display.mouse.getclick()
c.gcurve.visible = False

Also note the following from the documentation on graphs:

Every gdisplay has the attribute "display", so you can place
additional labels or manipulate the graphing window. The only objects
that you can place in the graphing window are labels, curves, faces,
and points.

graph1 = gdisplay()
label(display=graph1.display, pos=(3,2), text="P")
graph1.display.visible = False # make the display invisible

You can zoom in a graph (use left+right mouse buttons), just as in any
VPython display. You can't rotate, because it's a 2D display.

Finally, note that visual.graph is written in pure Python, so if you
have special needs you might consider making an improved version.
