在WxPython面板中嵌入matplotlib图 [英] Embedding a matplotlib figure inside a WxPython panel

问题描述

如何在WxPython面板中嵌入 matplotlib图形对象?

How do I embed a matplotlib figure object inside a WxPython panel?

我在Google上四处搜寻，并看到了涉及交互式图形和其他额外内容的复杂示例.有人可以举一个简单的例子吗?

I googled around and saw complicated examples involving interactive graphics and other extra stuff. Can anybody help with a minimal example?

推荐答案

这是带有matplotlib画布的面板的最小示例:

This is a minimal example for a Panel with a matplotlib canvas:

from numpy import arange, sin, pi
import matplotlib
matplotlib.use('WXAgg')

from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
from matplotlib.backends.backend_wx import NavigationToolbar2Wx
from matplotlib.figure import Figure

import wx

class CanvasPanel(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        self.figure = Figure()
        self.axes = self.figure.add_subplot(111)
        self.canvas = FigureCanvas(self, -1, self.figure)
        self.sizer = wx.BoxSizer(wx.VERTICAL)
        self.sizer.Add(self.canvas, 1, wx.LEFT | wx.TOP | wx.GROW)
        self.SetSizer(self.sizer)
        self.Fit()

    def draw(self):
        t = arange(0.0, 3.0, 0.01)
        s = sin(2 * pi * t)
        self.axes.plot(t, s)


if __name__ == "__main__":
    app = wx.PySimpleApp()
    fr = wx.Frame(None, title='test')
    panel = CanvasPanel(fr)
    panel.draw()
    fr.Show()
    app.MainLoop()
