Question

我想将matplotlib放入主tkinter窗口，但是经过大量的教程之后，我仍然在努力将matplotlib放在主窗口中。

我之所以需要它是因为我试图为学校项目制作图形软件。

任何帮助将不胜感激，这是我的代码到目前为止..

from tkinter import * #importing all files from Tkinter so all libraries are avaiable

root = Tk()           #root is a variable which equals a tkinter class - creates blank window

root.geometry('1600x900') # Size 1600, 900 for the window

 #-----------------------------------------------------------------------
 ---------------

 button1xy = Button(text="xy")
 buttony = Button(text="y=")
 buttonclrscrn = Button(text="clear screen")
 buttonbestfit = Button(text="line of best fit")#labels for the buttons



 button1xy.grid(row=0)
 buttony.grid(row=0, column=1)
 buttonclrscrn.grid(row=0, column=2)
 buttonbestfit.grid(row=0, column=3) #displaying them on the screen, 
 grid method


 menu = Menu(root)
 root.config(menu=menu)

 def dropdownmenu():
         submenu = Menu(menu)
         menu.add_cascade(label=">", menu=submenu)
         submenu.add_command(label="Linear")
         submenu.add_command(label="Polynomial")
         submenu.add_command(label="Trigonometrical")
         submenu.add_command(label="Percentage Error") #drop down menu 
         which appears in toolbar when button is clicked on


    buttonmenu = Button(text=">", command=dropdownmenu) #label and 
    command for the drop down menu button

    buttonmenu.grid(row=0, column=8) #grid method for it to display


     #-------------------------------------------------------------------


   root.mainloop() #continuously keeps window on the screen until closed
            #generates window

基本上，您正试图在Tkinter窗口中嵌入matplotlib图。需要注意的关键是你需要使用TkAgg后端进行matplotlib，这样才能在Tkinter中使用它。这是一个小例子，向您展示如何在Tkinter窗口中嵌入绘图并添加一个按钮：

import tkinter as tk
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
import matplotlib.pyplot as plt
import matplotlib
import math

def updateGraph():
    """Example function triggered by Tkinter GUI to change matplotlib graphs."""
    global currentGraph
    # Clear all graphs drawn in figure
    plt.clf()
    y = []
    if currentGraph == "sin":
        for i in x:
            y.append(math.cos(i))
        currentGraph = "cos"
    else:
        for i in x:
            y.append(math.sin(i))
        currentGraph = "sin"
    plt.plot(x,y)
    fig.canvas.draw()

# This defines the Python GUI backend to use for matplotlib
matplotlib.use('TkAgg')

# Initialize an instance of Tk
root = tk.Tk()

# Initialize matplotlib figure for graphing purposes
fig = plt.figure(1)

# Special type of "canvas" to allow for matplotlib graphing
canvas = FigureCanvasTkAgg(fig, master=root)
plot_widget = canvas.get_tk_widget()

# Example data (note: default calculations for angles are in radians)
x = []
for i in range(0, 500):
    x.append(i/10)
y = []
for i in x:
    y.append(math.sin(i))
plt.plot(x, y)

currentGraph = "sin"

# Add the plot to the tkinter widget
plot_widget.grid(row=0, column=0)
# Create a tkinter button at the bottom of the window and link it with the updateGraph function
tk.Button(root,text="Update",command=updateGraph).grid(row=1, column=0)

root.mainloop()

选择正弦/余弦波来显示Tkinter对象上的触发器，例如：按钮，可以操纵matplotlib图。

尝试在Tkinter中嵌入matplotlib时，这些链接非常有用：

我相信您会在以下链接中找到类似于您尝试执行的操作。经过一些搜索后，我发现它们在尝试在tkinter中插入图形并将它们视为帧时非常有用
