我有一个简单的动画图,如下所示:
import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
# First set up the figure, the axis, and the plot element we want to animate
fig = plt.figure()
ax = plt.axes(xlim=(0, 100), ylim=(0, 100))
line, = ax.plot([], [], lw=2)
x = []
y = []
# initialization function: plot the background of each frame
def init():
line.set_data([], [])
return line,
# animation function. This is called sequentially
def animate(i):
x.append(i + 1)
y.append(10)
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=200, interval=20, blit=True)
plt.show()
现在,这个程序运行得还好,但是我希望它能像这里一个子图一样扩展http://www.roboticslab.ca/matplotlib-animation/,其中x轴动态扩展以容纳传入的数据点。
我该如何实现这个功能?
ax.set_xlim(newxmin,newxmax)
来更改限制。 - ImportanceOfBeingErnest
