Question

我正在尝试使用正在类中创建的数字＆＃34; SubplotAnimation＆＃34;并把它放到我的图表页面，但它没有工作..请帮助我...这是我的代码（尝试采取所有不必要的东西，但有一些留下......）：

import matplotlib
matplotlib.use("TkAgg")
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
#import tkinter as tk
import Tkinter as tk

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.lines import Line2D
import matplotlib.animation as animation

class SubplotAnimation(animation.TimedAnimation):
    def __init__(self):
        fig = plt.figure()
        fig.set_size_inches(10, 7)
        ax2 = plt.subplot2grid((2, 2), (0, 0), colspan=2)
        ax3 = plt.subplot2grid((2, 2), (1, 0), colspan=2)

        self.t = np.linspace(0, 80, 400)
        self.x = np.cos(2 * np.pi * self.t / 10.)
        self.y = np.sin(2 * np.pi * self.t / 10.)
        self.z = 10 * self.t


        ax2.set_xlabel('y')
        ax2.set_ylabel('z')
        self.line2 = Line2D([], [], color='black')

        ax2.add_line(self.line2)

        ax2.set_xlim(0, 800)
        ax2.set_ylim(-1, 1)

        ax3.set_xlabel('x')
        ax3.set_ylabel('z')
        self.line3 = Line2D([], [], color='black')

        ax3.add_line(self.line3)

        ax3.set_xlim(0, 800)
        ax3.set_ylim(-1, 1)

        animation.TimedAnimation.__init__(self, fig, interval=50, blit=True)



    def _draw_frame(self, framedata):
        i = framedata

        self.line2.set_data(self.z[:i], self.y[:i])

        self.line3.set_data(self.z[:i], self.x[:i])


        self._drawn_artists = [self.line2, self.line3]

    def new_frame_seq(self):
        return iter(range(self.t.size))

    def _init_draw(self):
        lines = [self.line2, self.line3]
        for l in lines:
            l.set_data([], [])


#ani.save('test_sub.mp4')
    @property
    def fig(self):
        return self._fig

plt.show()





class MainPage(tk.Tk):

    def __init__(self, *args, **kwargs):

        root = tk.Tk.__init__(self, *args, **kwargs)

        tk.Tk.wm_title(self, "Heeeeelp")

        container = tk.Frame(self)

        container.pack(side="top", fill="both", expand=True)

        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)



        #********** FRAMES*******#

        self.frames = {} #empty..

        frame = GraphPage(container, self)

        self.frames[GraphPage] = frame

        frame.grid(row=0, column=0, sticky="nsew")

        self.show_frame(GraphPage)

    def show_frame(self, cont):

        frame = self.frames[cont]
        frame.tkraise()



class GraphPage(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self,parent)
        label = tk.Label(self, text="Help")
        label.grid(row=0, column=0, sticky='NW')


        ani = SubplotAnimation()
        canvas = FigureCanvasTkAgg(ani.fig, self)

        canvas.show()
        canvas.get_tk_widget().grid(row=1, column=0, rowspan=6, columnspan=3, sticky='NSEW')


app = MainPage()
app.geometry("980x640")

app.mainloop()

好的，需要做一些工作才能完成这项工作。

首先，我真的不明白为什么你有代码

@property
def fig(self):
    return self._fig

但我认为你需要删除它。同时删除它下方的plt.show()，因为它什么都不做。

然后您需要将fig中的SubplotAnimation重命名为self.fig：

self.fig = plt.figure()
self.fig.set_size_inches(10, 7)

最后，您应该拨打animation.TimedAnimation.__init__，将其放在canvas = FigureCanvasTkAgg(ani.fig, self)后面并将其更改为

animation.TimedAnimation.__init__(ani, ani.fig, interval=50, blit=True)

我认为这是使其发挥作用所需的所有步骤。

如果你想在SubplotAnimation类中保持动画的初始化，你也可以创建一个新函数来初始化它，如

def _init_animation(self):
    animation.TimedAnimation.__init__(self, self.fig, interval=50, blit=True)

使用

在canvas = FigureCanvasTkAgg(...)之后调用它

ani._init_animation()

在Matklotlib中嵌入Matplotlib并不会显示任何内容
