A simple widget for customtkinter to display radar chart, made with tkinter canvas. Fully custimasable widget, with resizability and theme colors.

What is a radar chart?

A radar chart, also known as a spider chart, web chart, is a graphical method used to display multivariate data. It consists of a sequence of equi-angular spokes, with each spoke representing one of the variables. The data length of a spoke is proportional to the magnitude of the variable for the data point relative to the maximum magnitude of the variable across all data points.

Installation

Download the source code, paste the CTkRadarChart folder in the directory where your program is present.

Usage

import customtkinter
from CTkRadarChart import *

root = customtkinter.CTk()

# Some labels that are shown at each axis
labels = ['Speed', 'Reliability', 'Comfort', 'Safety', 'Efficiency', 'Capacity']

# Create the RadarChart instance
chart = CTkRadarChart(root, labels=labels)
chart.pack(fill="both", expand=True)

# Add new data
chart.add_data("A", [90, 70, 90, 75, 60, 80])
chart.add_data("B", [60, 80, 70, 85, 75, 90])
