Python Tkinter : Embed a matplotlib plot in a widget

Question

我已经搜索过了，例如Python Tkinter Embed Matplotlib in GUI但还是想不通。基本上我试图在由 tkinter 组成的球员窗口内为篮球比赛的球员能力绘制一个精美的图表

    self.fig = Figure(figsize=(1.5,1.5))
    self.ax = self.fig.add_axes([0.025,0.025,0.95,0.95],polar=True)
    self.plot_widget = FigureCanvasTkAgg(self.fig, master=self.top)
    self.ax.grid(False)

    N = 5
    theta = np.arange(0.0, 2*np.pi, 2*np.pi/N)
    radii = [self.thisPlayer.rebounds,self.thisPlayer.freeThrows,self.thisPlayer.steal,self.thisPlayer.underRim,self.thisPlayer.distance]
    width = [2*np.pi/(N),2*np.pi/(N),2*np.pi/(N),2*np.pi/(N),2*np.pi/(N)]
    bars = pl.bar(0 , 20,width=2*np.pi, linewidth = 0) + pl.bar(theta, radii, width=width, bottom=0.2)

    for r,bar in zip(radii, bars):
        bar.set_facecolor( cm.jet(r/20.))
        bar.set_alpha(0.5)

    self.ax.set_xticklabels([])
    self.ax.set_yticklabels([])
    self.plot_widget.show()
    self.plot_widget.get_tk_widget().pack()

发生的情况是播放器窗口现在有绘图小部件，但未显示绘图。另一方面，只需绘制未嵌入 tkinter 中的功能就可以了。对不起我的英语不好。提前致谢

设置self.ax后，您需要调用self.ax.bar，而不是pl.bar来绘制条形图self.fig。这是一个可运行的示例:

import matplotlib.pyplot as plt
import numpy as np
import Tkinter as tk
import matplotlib.figure as mplfig
import matplotlib.backends.backend_tkagg as tkagg
pi = np.pi


class App(object):
    def __init__(self, master):
        self.master = master
        self.thisPlayer = Bunch(
            rebounds=20.0,
            freeThrows=5.0,
            steal=5.0,
            underRim=10,
            distance=10)
        self.fig = mplfig.Figure(figsize=(1.5, 1.5))
        self.ax = self.fig.add_axes([0.025, 0.025, 0.95, 0.95], polar=True)
        self.canvas = tkagg.FigureCanvasTkAgg(self.fig, master=master)
        self.ax.grid(False)

        N = 5
        theta = np.arange(0.0, 2 * pi, 2 * pi / N)
        radii = [self.thisPlayer.rebounds, self.thisPlayer.freeThrows,
                 self.thisPlayer.steal, self.thisPlayer.underRim,
                 self.thisPlayer.distance]
        width = [2 * pi / (N)] * 5
        bars = (
            # self.ax.bar(0, 20, width=2 * pi, linewidth=0) +
            self.ax.bar(theta, radii, width=width, bottom=0.2))
        cmap = plt.get_cmap('jet')
        for r, bar in zip(radii, bars):
            bar.set_facecolor(cmap(r / 20.))
            bar.set_alpha(0.5)
        self.ax.set_xticklabels([])
        self.ax.set_yticklabels([])
        self.canvas.get_tk_widget().pack()
        self.canvas.draw()


class Bunch(object):
    """
    http://code.activestate.com/recipes/52308
    foo=Bunch(a=1,b=2)
    """
    def __init__(self, **kwds):
        self.__dict__.update(kwds)


def main():
    root = tk.Tk()
    app = App(root)
    tk.mainloop()

if __name__ == '__main__':
    main()
