Embedding a matplotlib animation into a tkinter frame

Question

For a project I am working on a simple harmonic motion simulator (How a mass oscillates over time). I have got the data produced correctly and already have a graph produced within a tkinter frame work. At the moment it only shows a static graph where my objective is to display the graph as an animation over time.

So for ease sake I have created a mock up of the programme using the following code:

#---------Imports
from numpy import arange, sin, pi
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
from matplotlib.figure import Figure
import tkinter as Tk
from tkinter import ttk
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
#---------End of imports

fig, ax = plt.subplots()

x = np.arange(0, 2*np.pi, 0.01)        # x-array
line, = ax.plot(x, np.sin(x))

def animate(i):
    line.set_ydata(np.sin(x+i/10.0))  # update the data
    return line,

ani = animation.FuncAnimation(fig, animate, np.arange(1, 200), interval=25, blit=False)
#plt.show() #What I want the object in tkinter to appear as

root = Tk.Tk()

label = ttk.Label(root,text="SHM Simulation").grid(column=0, row=0)

canvas = FigureCanvasTkAgg(fig, master=root)
canvas.show()
canvas.get_tk_widget().grid(column=0,row=1)

Tk.mainloop()

This code will display the animation that I want in the tkinter frame work when the plt.show() is uncommented. I would like to be able to place that animation within the framework of tkinter.

I have also been on the matplotlib website and viewed all of the animation examples and none of them have helped. I have also looked on Embedding an animated matplotlib in tk and that has placed the tkinter button within pyplot figure, whereas I would like to place the figure within a tkinter frame.

So just to clarify, I would like to be able to place the animation produced when plt.show() is uncommented in a tkinter frame, ie root = tk().

I modified your code:

#---------Imports
from numpy import arange, sin, pi
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
from matplotlib.figure import Figure
import Tkinter as Tk
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
#---------End of imports

fig = plt.Figure()

x = np.arange(0, 2*np.pi, 0.01)        # x-array

def animate(i):
    line.set_ydata(np.sin(x+i/10.0))  # update the data
    return line,

root = Tk.Tk()

label = Tk.Label(root,text="SHM Simulation").grid(column=0, row=0)

canvas = FigureCanvasTkAgg(fig, master=root)
canvas.get_tk_widget().grid(column=0,row=1)

ax = fig.add_subplot(111)
line, = ax.plot(x, np.sin(x))
ani = animation.FuncAnimation(fig, animate, np.arange(1, 200), interval=25, blit=False)

Tk.mainloop()
