Changing the Link Background Colour

Made with Plotapi

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

Preamble

In [1]:
from plotapi import Sankey

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

Introduction

Until we mouseover a Plotapi Sankey link, what we actually see is the background colour. By default, this background colour is set to be the same as the link foreground colour, as defined by the colors parameter, which by default is "gradient".

Let's see how we can change this!

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

Dataset

Plotapi Sankey expects a list of dictionary items, these will define the flow between a source and a target.

In [2]:
links = [
    {"source":"Group A", "target":"Rank 1", "value": 1000},
    {"source":"Group B", "target":"Rank 1", "value": 300},
    {"source":"Group B", "target":"Rank 2", "value": 600},
    {"source":"Group B", "target":"Rank 3", "value": 400},
    {"source":"Rank 1", "target":"Club A", "value": 700},
    {"source":"Rank 1", "target":"Club B", "value": 400},
    {"source":"Rank 1", "target":"Club C", "value": 200},
    {"source":"Rank 2", "target":"Club B", "value": 200},
    {"source":"Rank 2", "target":"Club C", "value": 400},
    {"source":"Rank 3", "target":"Withdrawn", "value": 400},
    {"source":"Club A", "target":"The Most Amazing Prize", "value": 500},
]

We can add many source's and target's in any arrangement.

Visualisation

We can set the link background colour by passing a HEX colour code or string alias into the link_background_color parameter. Let's try setting the link background colour to grey.

Here we're using .show() which outputs to a Jupyter Notebook cell, however, we may want to output to an HTML file with .to_html() instead. More on the different output methods later!

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

In [5]:
Sankey(links, link_background_color="grey").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.
