带matplotlib的wxpython不'；初始化

我试图在

wxpython

中使用

matplotlib

，但出现了一些问题

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

class MplCanvasFrame(wx.Frame):
    def _init_(self,parent):
        wx.Frame._init_(self, parent, size=(600, 400),
                        title='Matplotlib Figure with Navigation Toolbar')
        self.figure = Figure()

        self.axes = self.figure.add_subplot(111)

        x = np.arange(0, 6, .01)
        y = np.sin(x**2)*np.exp(-x)
        self.axes.plot(x, y)
        self.canvas = FigureCanvas(self, -1, self.figure)
app = wx.App(redirect = False)
frame = MplCanvasFrame(None)
frame.Show()
app.MainLoop()

它根本不画曲线

但当我尝试这个：

曲线画出来了

为什么？

我认为问题在于

\uuuu init\uuuu

的拼写。每边应该有两个下划线（请注意，这在代码中的两个位置）。

请尝试拼写

\uuuu init\uuuu

，每边有两个下划线。谢谢，我很高兴stupid@acui145你能回答你自己的问题并接受答案吗？

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

app = wx.App()
frame = wx.Frame(None, title = 'dasf',size = (600, 400))
figure = Figure()
axes = figure.add_subplot(111)
x = np.arange(0, 6, .01)
y = np.sin(x**2)*np.exp(-x)
axes.plot(x, y)
canvas = FigureCanvas(frame, -1, figure)
frame.Show()
app.MainLoop()
