Linked data table

PlotAPI Chord supports a linked data table. This means as you hover over arcs and chords in the Chord diagram, a data table will be filtering in real-time to show more information.

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    {"source":"Rank 3", "target":"Withdrawn", "value": 400},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},

To make use of the linked data table, we need to provide some data in CSV format. This could be loaded through a file, directly in a string, or using a pandas DataFrame .to_csv(index=False).

data_table = '''Start,Destination,TV Rating,Image
,,9.0,<img src='https://datacrayon.com/images/data-is-beautiful/pokemon_thumbs/101.png'>
Group A,Rank 1,6.0,<img src='https://datacrayon.com/images/data-is-beautiful/pokemon_thumbs/192.png'>
Group A,Rank 1,5.0,<img src='https://datacrayon.com/images/data-is-beautiful/pokemon_thumbs/213.png'>'''


We'll enable the linked data table by passing data into the data_table parameter, and we'll modify the data_table_column_width by setting it to a smaller value of 80.

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 default settings can do! Try hovering over Group A and its link to Rank 1.

The data table mode includes the "locking" feature. Try clicking on the Group A node and you will see a padlock icon appear in the top right, and until you click somewhere again the current selection will persist.
