Directed chords

The default behaviour of PlotAPI chord is to represent both sides of a relationship with a single chord. However, it may be more suitable to use two different chords with arrows to indicate the dimension of a relationship.

Sample data

Let's import PlotAPI and load our sample data.

from plotapi import Chord

matrix = [
    [0, 5, 6, 4],
    [2, 0, 5, 4],
    [6, 5, 0, 4],
    [2, 4, 3, 0],

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


To enable directed mode, we only need to set the directed parameter to true.

Chord(matrix, names, directed=True, colors="spectral").show()
PlotAPI - Chord Diagram

The directed Chord diagram can be paired with reverse_gradients=True to make it easier to see where inbound/outbound relationships are coming from or going to.
