Python tkinter和matplotlib画布显示，但不显示导航工具栏和图表标题

我正在创建一个将matplotlib并入tkinter的程序。大多数程序都可以工作，包括显示图形的画布，但是，图形标题、导航工具栏和xy图例不显示。我想知道的代码部分就在脚本的底部：

toolbar = NavigationToolbar2TkAgg( canvas, root ) 
toolbar.update() 
canvas._tkcanvas.grid(row=9,column=0)
plt.xlabel('x label')
plt.ylabel('y label')
plt.title('Graph')
plt.show()

有人有什么建议吗？任何帮助都将不胜感激

我知道这个答案可能来得有点晚，但我最近也偶然发现了这个问题，下面是你可以做的：

关于工具栏的问题，我可以参考以下问题：

NavigationToolbar在内部调用.pack（），而pack（）和grid（）不能一起工作。但您可以在根框架上创建一个Tk.Frame并将工具栏打包到其中：

toolbar_frame = Tk.Frame(root)
toolbar_frame.grid(row=9,column=0)
toolbar = NavigationToolbar2TkAgg(canvas, toolbar_frame) 
toolbar.update() 

如果要显示轴标签，请调用plt.figure而不是figure。这在我的情况下起作用：

fig = plt.figure(figsize=(5,4), dpi=100) 

您编写代码的方式在我的设置中不起作用，因此我做了一些其他更改。结果如下所示：

我认为你们使用了许多不必要的进口产品，这可能会相互冲突，我的情况就是这样

从Tkinter导入*

和

将Tkinter作为Tk导入

。希望这有帮助
