python線條顔色不同_Matplotlib動畫：以不同顔色繪制線條

我現在有以下代碼來顯示曲線的增長：import numpy as np

import matplotlib.pyplot as plt

import mpl_toolkits.mplot3d.axes3d as p3

import matplotlib.animation as animation

def move_curve(i, line, x, y, z):

# Add points rather than changing start and end points.

line.set_data(x[:i+1], y[:i+1])

line.set_3d_properties(z[:i+1])

fig = plt.figure()

ax = fig.gca(projection='3d')

x = [1, 3, 8, 11, 17]

y = [7, 2, -5, 3, 5]

z = [5, 7, 9, 13, 18]

i = 0

line = ax.plot([x[i], x[i+1]], [y[i],y[i+1]], [z[i],z[i+1]])[0]

ax.set_xlim3d([1, 17])

ax.set_ylim3d([-5, 7])

ax.set_zlim3d([5, 18])

line_ani = animation.FuncAnimation(fig, move_curve, 5, fargs=(line, x, y, z))

plt.show()

我想用不同的顔色顯示不同的線條。另外，我想随着曲線的增長更新軸的長度。在

怎麼做？我是python新手，是以可能會遺漏一些簡單的東西。謝謝你的幫助！在
