view and then close the figure automatically in matplotlib?
提问by zmwang
I have to check whether my parameters setting is right, so I need to draw many plots, and for drawing these plots, I choose to use matplotlib. After each checking, I need to click the close button on the top left conner. It's trivial. So is there any method that can make the plot show in about 3 or 5 seconds and automatically close without clicking? I know about the plt.close(), but it doesn't work. Here is my code.
我要检查我的参数设置是否正确，所以我需要绘制很多图，为了绘制这些图，我选择使用matplotlib。每次检查后，我需要单击左上角的关闭按钮。这是微不足道的。那么有没有什么方法可以让绘图在大约 3 或 5 秒内显示并自动关闭而不单击？我知道plt.close()，但它不起作用。这是我的代码。
from math import *
import sys
import numpy as np
from scipy import special
import matplotlib.pyplot as plt
x1=[]
y1=[]
x2=[]
y2=[]
x3=[]
y3=[]
with open('fort.222','r') as f:
for line in f:
a,b=line.split()
x1.append(float(a))
y1.append(float(b))
n=int(sys.argv[1])
i=0
with open('fort.777','r') as f:
for line in f:
if i==0:
k1=float(line)
i=i+1
x1,y1=np.array(x1),np.array(y1)
z1=special.eval_hermite(n,x1*k1)*sqrt(1/(sqrt(pi)*pow(2,n)*factorial(n)))*sqrt(k1)*np.exp(-np.power(k1*x1,2)/2.)
plt.figure()
plt.plot(x1,z1)
plt.plot(x1,y1)
plt.plot(x1,np.zeros(len(x1)))
plt.title('single center & double center')
plt.xlim(x1.min(),x1.max())
plt.ylim(-max(abs(y1.min()-0.1),y1.max()+0.1),max(abs(y1.min()-0.2),y1.max()+0.2))
plt.xlabel('$\zeta$'+'/fm')
plt.legend(('single, n='+sys.argv[1],'double, n='+sys.argv[1]),loc=2,frameon=True)
plt.show()
plt.close()

Documentation on pyplot.show()reads:
matplotlib.pyplot.show(*args, **kw)Display a figure. When running in ipython with its pylab mode, display all figures and return to the ipython prompt.
In non-interactive mode, display all figures and block until the figures have been closed; in interactive mode it has no effect unless figures were created prior to a change from non-interactive to interactive mode (not recommended). In that case it displays the figures but does not block.
A single experimental keyword argument,
block, may be set toTrueorFalseto override the blocking behavior described above.
matplotlib.pyplot.show(*args, **kw)显示一个图形。当以 pylab 模式在 ipython 中运行时，显示所有图形并返回 ipython 提示符。
在非交互模式下，显示所有图形并阻止直到图形关闭；在交互模式下，除非在从非交互模式更改为交互模式（不推荐）之前创建图形，否则它无效。在这种情况下，它会显示数字但不会阻止。
单个实验性关键字参数
block可以设置为True或False覆盖上述阻塞行为。
So the solution is this:
所以解决方案是这样的：
plt.show(block=False)
plt.pause(3)
plt.close()
