matplotlib Animations and interactive plotting Basic animation with FuncAnimation
Example
The matplotlib.animation package offer some classes for creating animations. FuncAnimation creates animations by repeatedly calling a function. Here we use a function animate() that changes the coordinates of a point on the graph of a sine function.
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
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
myAnimation = animation.FuncAnimation(fig, animate, frames=np.arange(0.0, TWOPI, 0.1), \
interval=10, blit=True, repeat=True)
plt.show()
