wxPython+Matplotlib繪製折線圖表

使用Matplotlib在wxPython的Panel上繪製曲線圖,需要匯入:

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

import wx

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

class FirseFrame(wx.Frame):

  wx.Frame.__init__(self,parent,id,title,pos,size,style)

  self.InitUI()
  pass
 def InitUI(self):
  self.SetBackgroundColour('white')

  self.scorePanel = wx.Panel(self)
  scores = [89,98,70,80,60,78,85,90]
  sum = 0
  for s in scores:
   sum += s
  average = sum / len(scores)

  t_score = numpy.arange(1,len(scores) + 1,1)
  s_score = numpy.array(scores)

  self.figure_score = Figure()
  self.figure_score.set_figheight(3.6)
  self.figure_score.set_figwidth(7.8)
  self.axes_score = self.figure_score.add_subplot(111)

  self.axes_score.plot(t_score,s_score,'ro',t_score,'k')
  self.axes_score.axhline(y=average,color='r')
  self.axes_score.set_title(u'My Scores')
  self.axes_score.grid(True)
  self.axes_score.set_xlabel('T')
  self.axes_score.set_ylabel('score')
  FigureCanvas(self.scorePanel,-1,self.figure_score)

  self.frame.Show()
  return True
