我收到TypeError:“ Circle”对象不可迭代。我需要做什么?圆的大小必须可变并且与轴有关,所以matplotlib圆是唯一的选择(我想)。
答案 0 :(得分:0)
这是一个可能的解决方案(假设您在jupyter笔记本电脑中运行):
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
from IPython.display import HTML
xvalues = np.arange(4000000, 6000000+1000, 1000).tolist()
yvalues = [5000000]*2001
Acc_11 = xvalues
Acc_12 = yvalues
fig = plt.figure(figsize = (5,5))
axes = fig.add_subplot(111)
axes.set_xlim((0, 10000000))
axes.set_ylim((0, 10000000))
point = plt.Circle((4000000, 5000000), 60000, color = "black")
def init():
point.center = (5, 5)
axes.add_patch(point)
return point,
def ani(i):
point.center = (Acc_11[i],Acc_12[i])
return point
anim = FuncAnimation(fig,
ani,
init_func=init,
frames=200, #len(Acc_11),
interval=10)
HTML(anim.to_html5_video())
您可能希望将frames=200
更改为frames=len(Acc_11)
,但要花一些时间才能运行。
