[Matplotlib-users] wxList and FigureCanvasWx

[Engelsma, D. <D.Engelsma@LacksWheel.com>]

Hello -

 

I''ve got a wxDialog where, among other controls, I have a wxList and a
FigureCanvasWx. Depending on what single item is selected in the wxList, the
FigureCanvasWx should show the appropriate graph. It's important that the
matplotlib-generated graph stay in the dialog along with the other controls
(I don't want to generate a separate frame for the graph).

 

I don't want to have to recompute the graph using matplotlib to refresh the
FigureCanvasWx if the user selects a different item in the List. Is there a
way to generate the graphs, temporarily store the figures (without having to
write them to the hard drive using savefig),  and show the appropriate graph
based upon the List selection?

 

I thought about generating and saving the graphs to disk and then loading
them in and using them as bitmaps in the wxDialog when needed - however,
that doesn't seem very efficient as the program would have to access the
disk and load the bitmap every time the list selection changed.

 

If it helps, here's part of the code used in creating the FigureCanvasWx:

 

def __init__(self, parent):

        self._init_ctrls(parent) # Create all other dialog controls

        

        self.fig = Figure((4.7,4), 75)

        self.canvas = FigureCanvasWx(self, -1, self.fig)

        self.canvas.SetPosition(wxPoint(480,400))

 

 

Thanks in advance,
