語法繪製使用FuncAnimation

Question

我的代碼三點運動：

fig = plt.figure() 
ax = fig.add_subplot(111, projection='3d') 

def animate(i): 
    ax.set_data(ax.scatter(ptx1, pty1, ptz1, c='red'), 
     ax.scatter(ptx2, pty2, ptz2, c='blue'), 
     ax.scatter(ptx3, pty3, ptz3, c='green')) 

ani = FuncAnimation(fig, animate, frames=10, interval=200) 

plt.show() 

我試圖繪製三個點的運動。每個ptx/y/z/1/2/3是一個給出點座標的浮點列表。我只是不確定如何使用FuncAnimation來激活我的觀點。任何幫助將不勝感激！

簡單的例子。多次調用animate，並且每次您必須使用不同的數據才能看到動畫。

import matplotlib.pyplot as plt 
from matplotlib.animation import FuncAnimation 
import random 

# create some random data  
ptx1 = [random.randint(0,100) for x in range(20)] 
pty1 = [random.randint(0,100) for x in range(20)] 

fig = plt.figure() 
ax = fig.add_subplot(111) 

def animate(i): 
    # use i-th elements from data 
    ax.scatter(ptx1[:i], pty1[:i], c='red') 

    # or add only one element from list 
    #ax.scatter(ptx1[i], pty1[i], c='red') 

ani = FuncAnimation(fig, animate, frames=20, interval=500) 

plt.show()
