wxPython avec matplotlib

Exemple 1

import wx

import numpy
import matplotlib

from matplotlib.figure import Figure
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas

class TestFrame(wx.Frame):

    def __init__(self,parent,title):
        wx.Frame.__init__(self,parent,title=title,size=(800,800))

        self.figure = matplotlib.figure.Figure()
        self.axes = self.figure.add_subplot(111)
        x = numpy.arange(0.0,10,1.0)
        y = [0,1,1.7,3,4.1,5.2,6,6.7,7.5,9.2]
        self.axes.plot(x,y,'o--')
        self.canvas = FigureCanvas(self, -1, self.figure)

if __name__ == "__main__":
    app=wx.PySimpleApp()
    frame=TestFrame(None,"Hello Matplotlib !")
    frame.Show()
    app.MainLoop()
