matplotlib Save animation to gif


In this example we use the save method to save an Animation object using ImageMagick.

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
from matplotlib import rcParams

# make sure the full paths for ImageMagick and ffmpeg are configured
rcParams['animation.convert_path'] = r'C:\Program Files\ImageMagick\convert'
rcParams['animation.ffmpeg_path'] = r'C:\Program Files\ffmpeg\bin\ffmpeg.exe'

TWOPI = 2*np.pi

fig, ax = plt.subplots()

t = np.arange(0.0, TWOPI, 0.001)
s = np.sin(t)
l = plt.plot(t, s)

ax = plt.axis([0,TWOPI,-1,1])

redDot, = plt.plot([0], [np.sin(0)], 'ro')

def animate(i):
    redDot.set_data(i, np.sin(i))
    return redDot,

# create animation using the animate() function with no repeat
myAnimation = animation.FuncAnimation(fig, animate, frames=np.arange(0.0, TWOPI, 0.1), \
                                      interval=10, blit=True, repeat=False)

# save animation at 30 frames per second'myAnimation.gif', writer='imagemagick', fps=30)
