Embedding a matplotlib figure inside a WxPython panel

Question

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?

Answer 1

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() 

Answer 2

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))
...
