Node aligment
PlotAPI Sankey supports different layouts using the specification of node alignment.
Sample data
Let's import PlotAPI and load our sample data.
from plotapi import Sankey
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{"source":"Rank 3", "target":"Withdrawn", "value": 400},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},
]
Demonstration
We can change how our nodes are arranged using the node_alignment parameter. It supports the following settings: left, right, justify, and center. Let's demonstrate these below.
Right alignment
Sankey(links, colors="monsters", link_numbers=False,
node_alignment="right").show()
Justified alignment
Sankey(links, colors="monsters", link_numbers=False,
node_alignment="justify").show_png()
Center alignment
Sankey(links, colors="monsters", link_numbers=False,
node_alignment="center").show_png()
Left alignment
Sankey(links, colors="monsters", link_numbers=False,
node_alignment="left").show_png()
