Preamble¶
from plotapi import Sankey
Sankey.set_license("your username", "your license key")Introduction¶
The Plotapi Sankey diagram font-sizes changed independently.
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.
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{"source":"Rank 3", "target":"Withdrawn", "value": 400},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 sources and targets in any arrangement.
Visualisation¶
The font-sizes can be adjusted through a combination of the following:
-
title_font_size- to change the title font-size. -
node_font_size- to change the node label font-size. -
link_font_size- to change the link label font-size.
Let's demonstrate these in action.
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!
Sankey(links, title="Font-size demonstration",
node_font_size=10,
link_font_size=30,
title_font_size=30).show()Plotapi - Sankey Diagram
Below are the default sizes for reference.

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.
