MainWindow(frame,-1)

Try something like this ...

#plt.show()
        plt.savefig("test.png")

        # create an internal image
        image = wx.Bitmap("test.png")
        # show the image as static bitmap
        wx.StaticBitmap(self, wx.ID_ANY, image)

        perf_plot = 'test.png'

Also correct the error in line 63, needs a closing '

Thanks for ur response..Using this method seems to create half the image in the main panel and not in a new window hence my buttons being over the image etc.

In this case you have to create a new parent frame (size it for the image) for wx.StaticBitmap(frame, wx.ID_ANY, image)

Would be nice if I could test it out, but I simply don't have all the required modules and data files.

No joy still unfortunately. Seems like it is doing something but no new frame pops up and displays the image.

Got it to work now :)
