tkinter和matplotlib:直到在Linux下关闭程序，窗口才会显示 [英] tkinter and matplotlib: windows not showing until program closes under Linux

问题描述

我编写了一个程序，该程序基本上可以通过按不同的按钮来绘制不同的数据.该程序可以在Windows下按预期工作，但是当我尝试将其移植到Linux(Red Hat v6)时，我遇到了一个奇怪的问题:要绘制的窗口直到关闭主程序后才出现.不管我尝试绘制到哪个图形(图1,2等)，或者尝试键入plt.show()等，都会发生这种情况.

I've written a program that basically plots different data upon pressing different buttons. The program works as intended under Windows, but when I tried to port it to Linux (Red Hat v6) I'm getting a strange issue: the window that I want to plot does not appear until after I close the main program. This happens regardless of the figure (figure 1,2 etc.) I'm trying to plot to, or if I try to type plt.show() etc.

我编写的程序几乎有1000行代码，但是我创建了一个具有相同问题的缩写程序.它可以在Windows下运行，但是在Linux下，我必须关闭根窗口才能显示matplotlib窗口.

The program I've written is almost 1000 lines of code, but I created an abbreviated program that has the same problem. It works under Windows, but under Linux I have to close the root window for the matplotlib window to appear.

工作代码:

 import matplotlib.pyplot as plt 
 from tkinter import * 

 def click():
    x=['0','1','2']
    plt.plot(x,x)

 plotGUI=Tk()
 butt1=Button(plotGUI,text="Test", command=click).grid()
 plotGUI.mainloop()

推荐答案

我能够通过添加以下内容使其简单工作:

I was able to make it work simply by adding:

matplotlib.use('TkAgg')

这使该程序可以像Windows一样工作，而无需进行任何其他修改.我确实需要学习user3666197为将来的项目发布的概念.

This made the program work just as in Windows, without any other modifications necessary. I really need to learn the concepts posted by user3666197 for future projects though.
