MatPlotLib Plot w/Python Tkinter

Question

我正在尝试在与图像相同的窗口或画布中显示BMP图像的MatPlotLib图。代码已经可以显示图像，并且我已经有了数据图，但我只是无法将图嵌入到GUI中。我尝试引用http://matplotlib.org/examples/user_interfaces/embedding_in_tk2.html，但我有点难倒试图暗示它到这个代码。

理想情况下，我会在图像下方显示阴谋。

这里是我的代码：

import tkinter as tk 
from tkinter import * 
from tkinter import filedialog 
from PIL import Image, ImageTk 
from scipy import misc 
import os 
import numpy as np 
import matplotlib.pyplot as plt 
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg 
from matplotlib.figure import Figure 

class Window(Frame): 
    def __init__(self, master=None): 
     Frame.__init__(self, master) 

     self.master = master 
     self.pos = [] 
     self.master.title("BMP Image GUI") 
     self.pack(fill=BOTH, expand=1) 

     self.counter = 0 

     menu = Menu(self.master) 
     self.master.config(menu=menu) 

     # File Bar 
     file = Menu(menu) 
     file.add_command(label="Open Image 1", command=self.openImage1) 
     file.add_command(label="Exit", command=self.client_exit) 
     menu.add_cascade(label="File", menu=file) 

     self.canvas = tk.Canvas(self) 
     self.canvas.pack(fill=tk.BOTH, expand=True) 
     self.image = None 
     self.image2 = None 

    def client_exit(self): 
     exit() 

    def openImage1(self): 
     filename = filedialog.askopenfilename(initialdir=os.getcwd(), title="Select BMP File", 
               filetypes=[("BMP Files", "*.bmp")]) 
     if not filename: 
      return 

     # Image 1 Data Graph 
     image = misc.imread(filename, flatten=False, mode="RGB") 
     sumArray1 = [] 
     for i in range(0, image.shape[0]-1): 
      sumArray1.append(np.sum(image[i])) 
     np.asarray(sumArray1) 
     fig = plt.figure(figsize=(10,3.75), dpi=96) 
     plt.plot(sumArray1) 


     # Image 1 
     load = Image.open(filename) 
     load1 = load.resize((960, 720), Image.ANTIALIAS) 
     w, h = load1.size 
     width, height = root.winfo_screenmmwidth(), root.winfo_screenheight() 

     if self.image is None: 
      self.render = ImageTk.PhotoImage(load1) 
      self.image = self.canvas.create_image((w/2, h/2), image=self.render) 
      root.geometry("%dx%d" % (w, height)) 

root = tk.Tk() 
root.geometry("%dx%d" % (300, 300)) 
root.title("BMP Image GUI") 
app = Window(root) 
app.pack(fill=tk.BOTH, expand=1) 
root.mainloop()

我不知道这是否是有效的，但创造了一个第二画布作为canvas2，似乎做的工作。之前，我正在与BMP图像处理相同的画布，但没有显示出来。也许有一种方法只使用一个画布来完成。

if self.image is None: 
     self.render = ImageTk.PhotoImage(load1) 
     self.image = self.canvas.create_image((w/2, h/2), image=self.render) 
     root.geometry("%dx%d" % (w, height)) 
     self.canvas2 = FigureCanvasTkAgg(fig, master=root) 
     self.canvas2.show() 
     self.canvas2.get_tk_widget().pack(side=tk.BOTTOM, fill=tk.BOTH, expand=0) 
     self.canvas2._tkcanvas.pack(side=Tk.TOP, fill=Tk.BOTH, expand=0)
