title: plotting a scatter graph in wx.lib.plot
body: <p>I am wanting to draw a scatter graph in wxpython
  so far i have managed to draw a line graph. I do not now how to draw a scatter graph using wx.lib.plot
  any help would be appreciated</p>
  
  <pre><code>import wx
  import logging
  import wx.lib.plot as plot
  
  class PlotCanvasExample(plot.PlotCanvas):
  def __init__(self, parent, id, size):
      ''' Initialization routine for the this panel.'''
      plot.PlotCanvas.__init__(self, parent, id, style=wx.BORDER_NONE, size=desiredSize)
      self.data = [(1,2), (2,3), (3,5), (4,6), (5,8), (6,8), (10,10)]
      line = plot.PolyLine(self.data, legend='', colour='pink', width=2)
      gc = plot.PlotGraphics([line], 'Line Graph', 'X Axis', 'Y Axis')
      self.Draw(gc, xAxis=(0,15), yAxis=(0,15))
  
  class MyFrame(wx.Frame):
  def __init__(self, parent, id ,size):
      wx.Frame.__init__(self, parent, id, size=desiredSize)
      sizer = wx.BoxSizer(wx.VERTICAL)
      self.canvas = PlotCanvasExample(self, 0, size)
      sizer.Add(self.canvas, 1, wx.EXPAND, 0)
      self.SetSizer(sizer)
      self.Layout()
  
  if __name__ == '__main__':
  ''' Simple main program to display this panel. '''
  # Create a simple wxFrame to insert the panel into
  desiredSize = wx.Size(300,200)
  app = wx.PySimpleApp()
  frame = MyFrame(None, -1,  size=desiredSize)    
  frame.Show()
  app.MainLoop()
