How do I embed a matplotlib figure object inside a WxPython panel?
I googled around and saw complicated examples involving interactive graphics and other extra stuff. Can anybody help with a minimal example?

This is a minimal example for a Panel with a matplotlib canvas:
from numpy import arange, sin, pi
import matplotlib
matplotlib.use('WXAgg')
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
from matplotlib.backends.backend_wx import NavigationToolbar2Wx
from matplotlib.figure import Figure
import wx
class CanvasPanel(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent)
self.figure = Figure()
self.axes = self.figure.add_subplot(111)
self.canvas = FigureCanvas(self, -1, self.figure)
self.sizer = wx.BoxSizer(wx.VERTICAL)
self.sizer.Add(self.canvas, 1, wx.LEFT | wx.TOP | wx.GROW)
self.SetSizer(self.sizer)
self.Fit()
def draw(self):
t = arange(0.0, 3.0, 0.01)
s = sin(2 * pi * t)
self.axes.plot(t, s)
if __name__ == "__main__":
app = wx.PySimpleApp()
fr = wx.Frame(None, title='test')
panel = CanvasPanel(fr)
panel.draw()
fr.Show()
app.MainLoop()

Hey, can you write an option to set the size of the canvas too?
Defining the frame size:
if __name__ == "__main__":
app = wx.App()
fr = wx.Frame(None, title='test', size=wx.Size(806, 450))
panel = CanvasPanel(fr)
panel.draw()
fr.Show()
app.MainLoop()
or defining the panel size:
class CanvasPanel(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent,size=wx.Size(806, 450))
...
