Layout properties

Sample data

Let's import PlotAPI and load our sample data.

from plotapi import Chord

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"]

Demonstration

We can modify the width, margin, and rotation of our diagram.

The width parameter will also set the height, as the PlotAPI Chord maintains a $1:1$ ratio. The callout label style automatically adjusts the height for better presentation.

The margin parameter expects a single float to imply an equal margin of that size.

The rotate paramater will rotate the Chord diagram around its center.

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

By default a Chord diagram is centered, but this can be disabled with center=False.

With a title

Chord(matrix, names, colors="warm",
      title="Movie Genre Co-occurrence").show()

With layout properties

Chord(matrix, names, colors="cool",
      label_style="star",
      width=500, margin=50, rotate=-30).show()

Without layout properties

Chord(matrix, names, colors="cool").show()
