python - 如何在python tkinter中布局不规则定位的matplotlib条形图，不符合3x3网格

Question

以下 python 代码在两个滚动文本框和多个按钮后面显示了一个条形图。我在做python方面真的很新，我想知道是否可以调整图表的大小，以便：

(1) 它的左边缘与滚动文本框的右边缘对齐；

(2) 其顶部与按钮 3的顶部对齐；

(3) 它的底部与下滚动文本框的底部边缘对齐；和，

(4) 其右边缘与屏幕右边缘对齐。

ww.geometry('700x400')
ww.state('zoomed')

datalst = [31, 41, 59, 26, 53, 58, 97, 96, 36]
ff = Figure(figsize=(6,6), dpi=100)
xx = ff.add_subplot(111)
ind = np.arange(len(datalst))
rects1 = xx.bar(ind, datalst, 0.8)
canvas = FigureCanvasTkAgg(ff, master=ww)
canvas.draw()
canvas.get_tk_widget().pack()

butt1 = Button(ww,text='Button 1',command=dummy, height=1,width=20,state='normal')
butt1.place(x=12, y=2)
butt2 = Button(ww,text='Button 2',command=dummy, height=1,width=20,state='disabled')
butt2.place(x=162, y=2)

butt7.place(x=420, y=394)
butt8 = Button(ww,text='Button 8',command=dummy, height=1,width=12,state='disabled')
butt8.place(x=600, y=394)

disp_txt1 = tkst.ScrolledText(ww, width=36, height=12, wrap=tkinter.WORD, state='disabled')
disp_txt1.pack(fill=tkinter.BOTH)
disp_txt1.place(x=410, y=100)
disp_txt2 = tkst.ScrolledText(ww, width=36, height=5, wrap=tkinter.WORD, state='disabled')
disp_txt2.pack(fill=tkinter.BOTH)
disp_txt2.place(x=410, y=300)

ww.mainloop()

下面的橙色矩形显示了我想要图表的位置：

要执行该导入。请注意，以这种方式tkinter as tk导入总是好的，tkinter因为它不会namespaces 将 tkinter 导入为 tk。

这不是您需要指定要将其放置在窗口中可用空间的中间位置widget的错误。pack要做到这一点，canvas.get_tk_widget().pack(side=tk.RIGHT)这意味着屏幕的右侧。您可以查看该属性的文档。
