为了使您的示例起作用,您必须更改两件事:
从某处存储返回值
FuncAnimation
。否则你的动画会在plt.show()
.如果不想画线而只想画点,请
plt.plot
使用animation
from matplotlib.animation import FuncAnimation
import matplotlib.pyplot as plt
import numpy as np
fig, ax = plt.subplots()
ax.set_xlim(0,2)
ax.set_ylim(0,2)
line, = plt.plot(0,0,'bo')
def animation(i):
x=np.linspace(0,2,100)
y=np.linspace(0,1,100)
plt.plot(x[i],y[i],'bo')
return line,
my_animation=FuncAnimation(fig, animation, frames=np.arange(100),interval=10)
plt.show()
如果你只想在图表上有一个移动点,你必须设置并从inblit=True返回结果:plot.plotanimation
from matplotlib.animation import FuncAnimation
import matplotlib.pyplot as plt
import numpy as np
fig, ax = plt.subplots()
ax.set_xlim(0,2)
ax.set_ylim(0,2)
line, = plt.plot(0,0,'bo')
def animation(i):
x=np.linspace(0,2,100)
y=np.linspace(0,1,100)
return plt.plot(x[i],y[i],'bo')
my_animation=FuncAnimation(
fig,
animation,
frames=np.arange(100),
interval=10,
blit=True
)
plt.show()
此外,您可能想摆脱 (0,0) 处的点,并且不想为每个动画帧计算xand :y
from matplotlib.animation import FuncAnimation
import matplotlib.pyplot as plt
import numpy as np
fig, ax = plt.subplots()
ax.set_xlim(0,2)
ax.set_ylim(0,2)
x=np.linspace(0,2,100)
y=np.linspace(0,1,100)
def animation(i):
return plt.plot(x[i], y[i], 'bo')
my_animation=FuncAnimation(
fig,
animation,
frames=np.arange(100),
interval=10,
blit=True
)
plt.show()
