Setting the Title

Preamble

In [1]:
from plotapi import Chord

Chord.set_license("your username", "your license key")

Introduction

Plotapi Chord allows setting a title for the diagram by passing in a string.

As we can see, we have set our license details in the preamble with Chord.set_license()

Dataset

Chord expects a list of names (list[str]) and a co-occurence matrix (list[list[float]]) as input.

In [2]:
matrix = [
    [0, 5, 6, 4, 7, 4],
    [5, 0, 5, 4, 6, 5],
    [6, 5, 0, 4, 5, 5],
    [4, 4, 4, 0, 5, 5],
    [7, 6, 5, 5, 0, 4],
    [4, 5, 5, 5, 4, 0],
]

names = ["Action", "Adventure", "Comedy", "Drama", "Fantasy", "Thriller"]

It may look more clear if we present this as a table with the columns and indices labelled. This is entirely optional.

In [3]:
import pandas as pd
pd.DataFrame(matrix, columns=names, index=names)
Out[3]:
Action Adventure Comedy Drama Fantasy Thriller
Action 0 5 6 4 7 4
Adventure 5 0 5 4 6 5
Comedy 6 5 0 4 5 5
Drama 4 4 4 0 5 5
Fantasy 7 6 5 5 0 4
Thriller 4 5 5 5 4 0

Visualisation

To include a diagram title, we can pass the desired string into the title parameter.

Be sure to interact with the visualisation to see what the default settings can do!

In [4]:
Chord(matrix, names, title="Movie Genre Co-occurrence").show()
