I want to build a GUI to view matplotlib figures with forward and backward buttons. GUI is just similar to view images. To an extent, I could get the results I need. The problem is: that when I use the backward button(<<) the size of the figure increases and I could not find out why. Is there anyone out there who can help understand what is missing and fix the size so it does not increase? Following are the codes for reference: from tkinter import * import tkinter as tk from matplotlib.backends.backend_tkagg import (FigureCanvasTkAgg,NavigationToolbar2Tk) import matplotlib.pyplot as plt # Variables for line plots x= [1,2,3,4] y=[4,5,6,7] x1=[5,6,7,3,1] y1=[8,9,10,2,4] x2=[1,4,2,5,9,3] y2=[2,5,1,6,1,4] # Creating figures fig1,ax1 = plt.subplots() ax1.plot(x, y, marker='o', label="Data Points",color='red') ax1.set_title("Basic Components of Matplotlib Figure") ax1.set_xlabel("X-Axis") ax1.set_ylabel("Y-Axis") fig1.tight_layout() # plt.show() fig2,ax2 = plt.subplots() ax2.plot(x1, y1, marker='o', label="Data Points",color='green') ax2.set_title("Basic Components of Matplotlib Figure") ax2.set_xlabel("X-Axis") ax2.set_ylabel("Y-Axis") fig2.tight_layout() fig3,ax3 = plt.subplots() ax3.plot(x2, y2, marker='o', label="Data Points",color='orange') ax3.set_title("Basic Components of Matplotlib Figure") ax3.set_xlabel("X-Axis") ax3.set_ylabel("Y-Axis") fig3.tight_layout() fig_list = [fig1,fig2,fig3] def frwrd(number): global Fw_Btn global Bck_Btn global exit_btn global frame1 global Fig_Canvas frame1.destroy() # Creating a frame in root frame1= Frame(root,bg= "green") frame1.grid(row=1,column=0,columnspan=3,padx=10,pady=10,sticky='nsew') # Create a figure canvas again Fig_Canvas = FigureCanvasTkAgg(fig_list[number-1],master = frame1) Fig_Canvas.draw() Fig_Canvas.get_tk_widget().grid(row=0,column=0) # Creating buttons again Fw_Btn = Button(root, text = '>>',command=lambda:frwrd(number + 1)) Bck_Btn = Button(root, text = '<<',command= lambda: back(number - 1)) if number ==3: Fw_Btn = Button(root, text = '>>',state=DISABLED) Fw_Btn.grid(row=0,column=2,sticky='nswe') Bck_Btn.grid(row=0,column=0,sticky='nswe') exit_btn.grid(row=0,column=1,sticky='nswe') def back(number): global Fw_Btn global Bck_Btn global exit_btn global frame1 global Fig_Canvas frame1.destroy() # Creating a frame inplace of root frame1= Frame(root,bg= "green") frame1.grid(row=1,column=0,columnspan=3,padx=10,pady=10,sticky='nsew') # Create a figure canvas again Fig_Canvas = FigureCanvasTkAgg(fig_list[number-1],master = frame1) Fig_Canvas.draw() Fig_Canvas.get_tk_widget().grid(row=0,column=0) # Creating buttons again Fw_Btn = Button(root, text = '>>',command=lambda:frwrd(number + 1)) Bck_Btn = Button(root, text = '<<',command= lambda: back(number - 1)) if number ==1: Bck_Btn = Button(root, text = '<<',state=DISABLED) Fw_Btn.grid(row=0,column=2,sticky='nswe') Bck_Btn.grid(row=0,column=0,sticky='nswe') exit_btn.grid(row=0,column=1,sticky='nswe') # root of tkinter root = Tk() root.geometry('700x600') # Buttons Fw_Btn = Button(root, text = '>>',command=lambda: frwrd(2)) Bck_Btn = Button(root, text = '<<',command= back,state=DISABLED) exit_btn = Button(root,text = 'Exit',command= root.quit) # Placing buttons Bck_Btn.grid(row=0,column=0,sticky='nswe') exit_btn.grid(row=0,column=1,sticky='nswe') Fw_Btn.grid(row=0,column=2,sticky='nswe') # Creating a frame inplace of root frame1= Frame(root,bg= "green") frame1.grid(row=1,column=0,columnspan=3,padx=10,pady=10,sticky='nsew') # Creating a figure canvas Fig_Canvas = FigureCanvasTkAgg(fig1,master = frame1) Fig_Canvas.draw() Fig_Canvas.get_tk_widget().grid(row=0,column=0) # Configureing the root root.grid_columnconfigure([0,1,2],weight=1) root.grid_rowconfigure(1,weight=1) root.mainloop() Continue reading...
