如何连续检查在foor回路中绘制的图（无子图！）？

Question

我有几个主题的数据，想为每个主题作图。目标是遍历各个主题，提取当前主题的数据，然后绘制。绘制第一个主题的数据后，程序应停止并等待用户输入，以便可以安心地检查该主题的图。这怎么可能？

注意：我对创建子图不感兴趣。 我正在使用PyCharm和TkAgg后端。

import matplotlib.pyplot as plt
import numpy as np


data_per_subject = [np.array([1,2]),
                    np.array([3,4]),
                    np.array([5,6])]

for data in data_per_subject:
    # open figure and plot data of current subject
    fig, ax = plt.subplots() 
    plt.plot(data) 

    # Here some magic has to take place, so that the program waits for my 
    # input. The importent thing is, that I have to be able to inspect 
    # the plot for the current subject while the programm is waiting for my 
    # input!

    # close figure
    plt.close()
