python – for循环中的Matplotlib动画?

导读:我试图通过动画在for循环中绘制一些数据.我希望它等到动画结束然后继续进行for循环.暂停似乎有效,但有时电影很长,我想关闭并转移到下一个.谁知道我怎么能做到这一点? import numpy as npfrom matplotlib import pyplot as pltfrom matplotlib import animat

我试图通过动画在for循环中绘制一些数据.我希望它等到动画结束然后继续进行for循环.暂停似乎有效,但有时电影很长,我想关闭并转移到下一个.谁知道我怎么能做到这一点?
import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
import time
for j in range(0,2):
fig = plt.figure(j)
mngr = plt.get_current_fig_manager()
mngr.window.setGeometry(j*256,256,256)
ax = plt.axes(xlim=(0,2),ylim=(-2,2))
line,= ax.plot([],[],lw=2)
# initialization function: plot the background of each frame
def init():
line.set_data([],[])
return line,# animation function. This is called sequentially
def animate(i):
x = np.linspace(0,2,1000)
y = np.sin(2 * np.pi * (x - 0.01 * i+j/4.))
line.set_data(x,y)
return line,# call the animator. blit=True means only re-draw the parts that have changed.
anim = animation.FuncAnimation(fig,animate,init_func=init,frames=200,interval=20,blit=True,repeat=False)
plt.pause(0.02*200)
plt.show(block=True)
解决方法
一种方法是使用KeyboardInterrupt异常移动到下一个图.
为了更好的可读性,将绘图移动到一个函数中: import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation
import time
def animate_multi(j):
fig = plt.figure(j)
mngr = plt.get_current_fig_manager()
mngr.window.setGeometry(j*256,256)
ax = plt.axes(xlim=(0,2))
line,lw=2)
# initialization function: plot the background of each frame
def init():
line.set_data([],[])
return line,# animation function. This is called sequentially
def animate(i):
x = np.linspace(0,1000)
y = np.sin(2 * np.pi * (x - 0.01 * i+j/4.))
line.set_data(x,y)
return line,# call the animator. blit=True means only re-draw the parts that have changed.
anim = animation.FuncAnimation(fig,repeat=False)
plt.pause(0.02*200)
plt.close()
plt.show(block=True)
现在,在除了KeyboardInterrup之外的循环中继续下一个动画: for j in range(5):
try:
print('Working on plot',j)
animate_multi(j)
except KeyboardInterrupt:
plt.close()
注意:您可能必须按< Ctrl> – < C>两次跳到下一个动画. (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
