Error in matplotlib popup window (AttributeError: 'NoneType' object has no attribute 'set_canvas')

Question

I tried to plot the graph in pop up window. It pops up. But there is an error.

import tkinter as tk
window = tk.Tk()
window.configure(background=\'white\')

You didn't show how you create your class for plotting, so i can only go by assumption here. First create a empty list:

import tkinter as tk
window = tk.Tk()
window.configure(background='white')
figure_holder = []

Then append to the list when you create your figure:

def plot_sheets(self):
    for i in range(len(self.sheets)):
        a = self.sheets[i].plot_sheet()
        figure_holder.append(a)

Retrieve the figure object from the list when you plot it:

def cal_culate1():

    fig = figure_holder[0]

    dataPlot = FigureCanvasTkAgg(fig, master = window)
    #dataPlot.show()
    dataPlot.get_tk_widget().pack(side='top', fill='both', expand=1)
