Creating animated GIF files out of D3.js animations in Matplotlib
To create animated GIF files out of D3.js animation, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Create a new figure or activate an existing figure.
- Add an axes to the current figure and make it the current axes.
- Plot a line with empty lists.
- To initialize the line, pass empty lists.
- To animate the sine curve, update the sine curve values and return the line instance.
- Get a movie writer instance using PillowWriter() class.
- Save the .gif file using PillowWriter.
Example
import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
fig = plt.figure()
ax = plt.axes(xlim=(0, 2), ylim=(-2, 2))
line, = ax.plot([], [], lw=2)
def init():
line.set_data([], [])
return line,
def animate(i):
x = np.linspace(0, 2, 1000)
y = np.sin(2 * np.pi * (x - 0.01 * i))
line.set_data(x, y)
return line,
ani = animation.FuncAnimation(fig, animate, init_func=init, frames=200, interval=20, blit=True)
writer = animation.PillowWriter(fps=25)
ani.save("sine.gif", writer=writer)Output
