This is a sample showing how to embed a matplotlib figure in a wxPanel.

The example implements the full navigation toolbar, so you can automatically

inherit standard matplotlib features such as the ability to zoom, pan and
save figures in the supported formats.

There are a few small complexities worth noting in the example:

  1. By default, a wxFrame can contain a toolbar (added with SetToolBar())

    but this is at the top of the frame. Matplotlib default is to put the
    controls at the bottom of the frame, so you have to manage the toolbar
    yourself. I have done this by putting the figure and toolbar into a

    sizer, but this means that you need to override GetToolBar for your
    wxFrame so that the figure manager can find the toolbar.

  2. I have implemented a figure manager to look after the plots and axes.

    If you don’t want a toolbar, it is simpler to add the figure directly
    and not worry. However, the figure manager looks after clipping of the
    figure contents, so you will need it if you want to navigate

  3. There is a bug in the way in which my copy of wxPython calculates
    toolbar width on Win32, so there is a tricky line to ensure that the
    width of the toolbat is the same as the width of the figure.

  4. Depending on the parameters you pass to the sizer, you can make the
    figure resizable or not.

import matplotlib
from matplotlib.backends.backend_wx import Toolbar, FigureCanvasWx,\


from matplotlib.figure import Figure
from matplotlib.axes import Subplot
import matplotlib.numerix as numpy
import wx

class PlotFigure(wx.Frame):
def init(self):

    wx.Frame.__init__(self, None, -1, "Test embedded wxFigure")

    self.fig = Figure((9,8), 75)
    self.canvas = FigureCanvasWx(self, -1, self.fig)
    self.toolbar = Toolbar(self.canvas


    # On Windows, default frame size behaviour is incorrect
    # you don't need this under Linux
    tw, th = self.toolbar.GetSizeTuple()
    fw, fh = self.canvas.GetSizeTuple()
    self.toolbar.SetSize(wx.Size(fw, th))

    # Create a figure manager to manage things
    self.figmgr = FigureManager(self.canvas, 1, self)
    # Now put all into a sizer

    sizer = wx.BoxSizer(wx.VERTICAL)
    # This way of adding to sizer allows resizing
    sizer.Add(self.canvas, 1, wx.LEFT|wx.TOP|wx.GROW)
    # Best to allow the toolbar to resize!

sizer.Add(self.toolbar, 0, wx.GROW)

def plot_data(self):
    # Use ths line if using a toolbar
    a = self.fig.add_subplot(111)

    # Or this one if there is no toolbar

    #a = Subplot(self.fig, 111)

    t = numpy.arange(0.0,3.0,0.01)
    s = numpy.sin(2*numpy.pi*t)
    c = numpy.cos(2*numpy.pi*t)


def GetToolBar(self):
    # You will need to override GetToolBar if you are using an
    # unmanaged toolbar in your frame
    return self.toolbar
