我正在尝试在用Python编码的Tkinter GUI中嵌入一个绘图.我相信下面的代码只是简单地将图形放入画布中,但我没有对GUI网格中的画布位置进行任何控制.我希望能够将我的GUI的子部分作为情节...而不是整个部分.如何定位此画布小部件？

#!/usr/apps/Python/bin/python
import matplotlib, sys
matplotlib.use('TkAgg')
from numpy import arange, sin, pi
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
from matplotlib.figure import Figure
from Tkinter import *

master = Tk()
master.title("Hello World!")
#-------------------------------------------------------------------------------

f = Figure(figsize=(5,4), dpi=100)
a = f.add_subplot(111)
t = arange(0.0,3.0,0.01)
s = sin(2*pi*t)
a.plot(t,s)


dataPlot = FigureCanvasTkAgg(f, master=master)
dataPlot.show()
dataPlot.get_tk_widget().pack(side=TOP, fill=BOTH, expand=1)
#-------------------------------------------------------------------------------
master.mainloop()

我想知道是否有人知道为什么下面的代码按下GUI上的按钮后没有显示带有一行的图形.我想创建一个程序,在通过单击按钮导入一组数据后执行一长串命令.这些命令之一是在同一窗口内的图形上显示光谱数据.这是我到目前为止:

# import modules that I'm using
import matplotlib
matplotlib.use('TKAgg')
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationToolbar2TkAgg
from matplotlib.figure import Figure

# lmfit is imported becuase parameters are allowed to depend on each other along with bounds, etc.
from lmfit import minimize, Parameters, Minimizer
