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. " + 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.
