wxpython绘制折线图

environment：win10 + eclipse + pydev + python2.7.11 + wxpython3.0.2

code sample:

 #!/usr/bin/env python
 # -*- coding: UTF-8 -*-

 import wx
 import wx.lib.plot as plot

 class MyFrame(wx.Frame):
     def __init__(self):
         self.frame1 = wx.Frame(None, title="test", id=-1, size=(500, 300))
         self.panel1 = wx.Panel(self.frame1)
         self.panel1.SetBackgroundColour("white")

         Button1 = wx.Button(self.panel1, -1, "Update", (200,220))
         Button1.Bind(wx.EVT_BUTTON, self.redraw)

         plotter = plot.PlotCanvas(self.panel1)
         plotter.SetInitialSize(size=(500, 200))

         data= [[1, 10], [2, 5], [3,10], [4, 5]]
         line= plot.PolyLine(data, colour='red', width=1)

         gc= plot.PlotGraphics([line], 'Test', 'x', 'y')
         plotter.Draw(gc)

         self.frame1.Show(True)

     def redraw(self, event):
         plotter = plot.PlotCanvas(self.panel1)
         plotter.SetInitialSize(size=(500, 200))

         data2= [[1, 20], [2, 15], [3,20], [4, -10]]
         line= plot.PolyLine(data2, colour='red', width=1)

         gc= plot.PlotGraphics([line], 'Test', 'x', 'y')
         plotter.Draw(gc)

 app = wx.PySimpleApp()
 f = MyFrame()
 app.MainLoop()

error 1:raise ImportError("NumPy not found.\n" + msg)

solution: run console with"cmd", and run 'pip install numpy'.

error 2:TypeError: Required argument 'type' (pos 2) not found

solution:that's A BUG with wx3.0.2!

patch the latest wx.lib.plot can totally solve that.
