将Matplotlib从wxglade添加到面板

您好，我正在尝试从下面的链接添加matplotlib图表示例

在使用WXGlade生成的wxpython帧内创建面板。面板是需要图表的面板22。有什么建议吗

    class MyFrame1(wx.Frame):
    def __init__(self, *args, **kwds):
        # begin wxGlade: MyFrame1.__init__
        kwds["style"] = wx.DEFAULT_FRAME_STYLE

        self.panel_22 = wx.Panel(self, wx.ID_ANY)

        self.__set_properties()
        self.__do_layout()
        # end wxGlade

    def __set_properties(self):
        # begin wxGlade: MyFrame1.__set_properties
        self.SetTitle(_("frame_2"))
        # end wxGlade

    def __do_layout(self):
        # begin wxGlade: MyFrame1.__do_layout
        sizer_21 = wx.BoxSizer(wx.VERTICAL)
        grid_sizer_4 = wx.GridSizer(3, 3, 0, 0)
        grid_sizer_4.Add(self.panel_22, 1, wx.EXPAND, 0)
        sizer_21.Add(grid_sizer_4, 1, wx.EXPAND, 0)
        self.SetSizer(sizer_21)
        sizer_21.Fit(self)
        self.Layout()
        # end wxGlade

    # end of class MyFrame1
if __name__ == "__main__":
    gettext.install("app") # replace with the appropriate catalog name

    app =  wx.App(False)
    wx.InitAllImageHandlers()
    frame_2 = MyFrame1(None, wx.ID_ANY, "")
    app.SetTopWindow(frame_2)
    frame_2.Show()
    app.MainLoop()

它是否是在林间空地上产生的似乎并不重要。所以试试看

先添加两个导入

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

然后在_do_布局的开头添加两行：

def __do_layout(self):

    self.figure = Figure()
    self.canvas = FigureCanvas(self,panel_22, -1, self.figure)

    # begin wxGlade: MyFrame1.__do_layout

你看过例子了吗？谢谢你的otterb，但是我现在得到了一个名称错误：全局名称“Panel_22”没有定义。当我改变了自我，Panel_22太自我了。Panel_22成功了！谢谢
