I want to add a scrollbar that will move the yview of self.MyNetsCanvas. I got the scrollbar linked to the canvas but it's still not working. Also heads up you'll need a json file in order for this to work I added the json code below my python.
Appreciate the help.

Sorry for the long code.

Here is an example with canvas.create_text instead of labels:
from tkinter import *
import json
y = 0
def on_mousewheel(event):
canvas.yview_scroll(-event.delta // 120, "units")
print(event.delta)
root = Tk()
root.geometry("1600x900")
root.title("VerticalScrolledFrame Sample")
frame = Frame(root)
frame.pack(expand=True, fill=BOTH)
canvas = Canvas(frame, scrollregion=(0, 0, 0, 10000))
canvas.bind_all("<MouseWheel>", on_mousewheel)
with open("user.json") as f:
data = json.load(f)
temp = data['networks']
for network in data['networks']:
for key, value in network.items():
y = 30
canvas.create_text(20, 50 y, text=f'{key}: {value}', fill="black", anchor="w", font=("Roboto", 14))
vbar = Scrollbar(frame, orient=VERTICAL)
vbar.pack(side=RIGHT, fill=Y)
vbar.config(command=canvas.yview)
canvas.config(yscrollcommand=vbar.set)
canvas.pack(side=LEFT, expand=True, fill=BOTH)
root.mainloop()

Nevermind I figured it out I just have to add a frame inside the canvas and make sure it was bigger than the canvas.
