Plotapi, beautiful by default.

Let plotapi do the heavy lifting – enabling beautiful interactive visualisations with a single line of code (instead of hundreds).

Changing Ribbon Opacity

Contents

You can create beautiful, interactive, and engaging visualisations like this one with Plotapi in any programming language.

Preamble¶

In [1]:
from plotapi import Chord

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

Introduction¶

We can change the opacity of the inner section of our Chord diagram, or the ribbons. The opacity will change on mouseover to highlight the selected connections.

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¶

The opacity parameter controls the ribbon opacity for Chord. This value must be a float between or equal to $0.0$ and $1.0$.

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

In [4]:
Chord(matrix, names, opacity=0.2).show()

You can do so much more than what's presented in this example, and we'll cover this in later sections. If you want to see the full list of growing features, check out the Plotapi Documentation. and the Plotapi Gallery.
