[Visualpython-users] Clear points

[Poul R. <Pou...@sk...>]

How can I clear points, lines and even horizontal bars in a graph window
before redrawing?

Yours,

This isn't documented, so you need to look at the visual.graph module, 
but you'll find that these graphing objects are built on standard 
objects, so you can make them invisible. For example,

g = gcurve(....)
....
g.curve.visible = 0

The module should be revised to let you say directly g.visible = 0.

I use the next technique:

Examples:
#update plot population
        for dot in self.clgraph.dots:
            dot.visible=False
        self.clgraph.dots=[]
        del self.clgraph.dots
        del self.clgraph
        self.clgraph = gdots(gdisplay=self.clwindow)
        for cl in self.Population:
            col = color.white
            if cl.Relevance>0.0:
                col = color.red
            self.clgraph.plot(pos=cl.state,color=col)

        self.Gtrajectory.gcurve.visible = False
        del self.Gtrajectory
        self.Gtrajectory = gcurve(gdisplay=self.clwindow,color=color.yellow)



Hope this helps.
Kind regards...
