Question

我尝试在用Python编码的 Tkinter GUI中嵌入烛台和音量图表（使用 matplotlib ）。我尝试将这些网站作为参考：http://matplotlib.org/examples/user_interfaces/embedding_in_tk.html http://matplotlib.org/examples/user_interfaces/embedding_in_tk2.html

并在此处找到了其他解决方案，但我仍有一些问题。单独工作一切都很好，但是当我试图将它们组合在一起时，会出现两个窗口（一个用于图表，另一个用于带有一些小部件的Tkinter框架）而不是一个。
