[英]Trying to make a gif in Python
這可以使用matplotlib.animation來完成。
編輯
我將向您展示如何繪制 x 的偶次冪,例如x^2
、 x^4
等。 看看下面的例子:
import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
# Setting up the figure, the axis, and the plot element we want to animate
fig = plt.figure()
ax = plt.axes(xlim=(-10, 10), ylim=(-10, 1000))
line, = ax.plot([], [], lw=2)
# initialization method: plot the background of each frame
def init():
line.set_data([], [])
return line,
# animation method. This method will be called sequentially
pow_ = 2
def animate(i):
global pow_
x = np.linspace(-10, 10, 1000)
y = x**pow_
pow_+=2
line.set_data(x, y)
return line,
# call the animator. blit=True means only re-draw the parts that have changed.
anim = animation.FuncAnimation(fig, animate, init_func=init,
frames=10, interval=200, blit=True)
# if you want to save this animation as an mp4 file, uncomment the line bellow
# anim.save('basic_animation.mp4', fps=30, extra_args=['-vcodec', 'libx264'])
plt.show()
