Key
Animate a Line
import matplotlib.pyplot as plt
fig = plt.figure() ax = fig.add_subplot(111, projection='3d') # create a 3d grpah and add it to the fig
# Get the line longer and longer # line: [1,1,1] -> [ i * 10, i * 10, i * 10]
for i in range(100): x = [1, i * 10] y = [1, i * 10] z = [1, i * 10]
ax.clear() # clean the screen ax.plot(x, y, z, label='line')
plt.show() plt.show(block=False) plt.pause(0.1) # update & repair and then wait 0.1 seconds |
Code
File: test.py
import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D
fig = plt.figure() ax = fig.add_subplot(111, projection='3d') # create a 3d grpah and add it to the fig
for i in range(100): if i%2 == 0: bb = 100 else: bb = -100
x = [1, bb] y = [1, bb] z = [1, bb]
ax.clear() # clean the screen ax.set(xlim=(-500, 500), ylim=(-500, 500), zlim=(-500, 500)) # setup the scale ax.set_xlabel('$X$', fontsize=20) # repaint the axis label ax.set_ylabel("$Y$ axis label") ax.set_zlabel("$Z$ axis label") ax.plot(x, y, z, label='line') ax.legend() # show the legend plt.show(block=False) plt.pause(0.1) # update & repair and then wait 0.1 seconds
