动画移动点错误 [英] animation moving point error
本文介绍了动画移动点错误的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我是Python的初学者.我正在尝试制作一个沿水平方向移动的点的动画.但是,当我运行代码时,收到以下错误:
I am a beginner to Python. I'm trying to make an animation of a point moving in the horizontal direction. But, when I ran the code I received the below error:
TypeError: 'PathCollection' object is not iterable
我不知道如何解决它.
#----------------------------------------------------------------------
import numpy as np
import matplotlib
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
Acc_11 = [1,2,3,4,6,7]
lenAcc11 = len(Acc_11)
Acc_12 = [2,2,2,2,2,2]
# Scatter plot
fig = plt.figure(figsize = (5,5))
ax = plt.axes()
scat = ax.scatter([],[])
#initial func
def init():
return scat
#animation func
def ani (i):
for i in range(0,lenAcc11):
acc_11 = Acc_11[i]
print (acc_11)
acc_11_pos = Acc_12[i]
print (acc_11_pos)
scat = scat.set_data(acc_11,acc_11_pos)
return scat
ani = FuncAnimation(fig, ani, init_func = init, interval = 10, blit =True)
plt.show()

推荐答案
显示所有点
这显示了所有要点:
Show all points
This shows all points:
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
Acc_11 = [1,2,3,4,6,7]
Acc_12 = [2,2,2,2,2,2]
# Scatter plot
fig = plt.figure(figsize = (5,5))
def ani(coords):
return plt.scatter([coords[0]],[coords[1]], color='g')
def frames():
for acc_11_pos, acc_12_pos in zip(Acc_11, Acc_12):
yield acc_11_pos, acc_12_pos
ani = FuncAnimation(fig, ani, frames=frames, interval=1000)
plt.show()
仅显示一个移动点
这一次只显示一个点:
Show only one moving point
This shows only one point at a time:
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
Acc_11 = [1,2,3,4,6,7]
Acc_12 = [2,2,2,2,2,2]
# Scatter plot
fig = plt.figure(figsize = (5,5))
axes = fig.add_subplot(111)
axes.set_xlim(min(Acc_11), max(Acc_11))
axes.set_ylim(min(Acc_12), max(Acc_12))
point, = axes.plot([Acc_11[0]],[Acc_12[0]], 'go')
def ani(coords):
point.set_data([coords[0]],[coords[1]])
return point
def frames():
for acc_11_pos, acc_12_pos in zip(Acc_11, Acc_12):
yield acc_11_pos, acc_12_pos
ani = FuncAnimation(fig, ani, frames=frames, interval=1000)
plt.show()
