I want to create a GUI that allows me to read a text file into a variable by pressing a button. Then, I want to plot a histogram out of the data from the text file. The text file is just a 1D array of many values. Here is what I have so far:
Note: this is my first time dealing with Tkinter, so if there are better way to do this, I am open to suggestions.
from tkinter import * from tkinter import ttk from tkinter import filedialog import matplotlib.pyplot as plt root = Tk() root.geometry('800x800') def openfile(): global peaks filename = filedialog.askopenfilename() peaks = open(filename).read() def plot(): fig2,ax2 = plt.subplots() ax2.hist(peaks,1000) button = ttk.Button(root, text="Open", command=openfile) button.grid(column=1, row=1) plot = ttk.Button(root,text='Plot',command = plot) plot.grid(column=2,row=1) root.mainloop()From what I have at the moment, it seems like I can open a file, but I am not sure if it is being read into the global variable peaks. Then, when I press the Plot button, the code just stalls and then crashes. I need help with figuring out what I am doing wrong. Thank you.
