#!/usr/bin/env python
An example of how to use wx or wxagg in an application with the new
toolbar - comment out the setA_toolbar line for no toolbar

# matplotlib requires wxPython 2.8+
# set the wxPython version in lib\site-packages\wx.pth file
# or if you have wxversion installed un-comment the lines below
#import wxversion

from numpy import arange, sin, pi

import matplotlib

# uncomment the following to use wx rather than wxagg
#from matplotlib.backends.backend_wx import FigureCanvasWx as FigureCanvas

# comment out the following to use wx rather than wxagg
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas

from matplotlib.backends.backend_wx import NavigationToolbar2Wx

from matplotlib.figure import Figure

import wx
import wx.lib.mixins.inspection as WIT

class CanvasFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1,
                          'CanvasFrame', size=(550, 350))

        self.figure = Figure()
        self.axes = self.figure.add_subplot(111)
        t = arange(0.0, 3.0, 0.01)
        s = sin(2 * pi * t)

        self.axes.plot(t, s)
        self.canvas = FigureCanvas(self, -1, self.figure)

        self.sizer = wx.BoxSizer(wx.VERTICAL)
        self.sizer.Add(self.canvas, 1, wx.LEFT | wx.TOP | wx.EXPAND)

        self.add_toolbar()  # comment this out for no toolbar

    def add_toolbar(self):
        self.toolbar = NavigationToolbar2Wx(self.canvas)
        # By adding toolbar in sizer, we are able to put it at the bottom
        # of the frame - so appearance is closer to GTK version.
        self.sizer.Add(self.toolbar, 0, wx.LEFT | wx.EXPAND)
        # update the axes menu on the toolbar

# alternatively you could use
#class App(wx.App):
class App(WIT.InspectableApp):
    def OnInit(self):
        'Create the main window and insert the custom frame'
        frame = CanvasFrame()

        return True

app = App(0)
