Pulled out arcs
PlotAPI Chord supports pulling out arcs as a way to highlight or group elements.
Sample data
Let's import PlotAPI and load our sample data.
from plotapi import Chord
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"]
Demonstration
Pulling arcs can be controlled with the pull parameter. It expects a list of floats, one for each arc, indicating how far out to pull.
Let's pull out the Adventure arc by 50px. It's the second item in our names list above, so we'll adjust the second position.
Chord(matrix, names, pull=[0, 50, 0, 0, 0, 0]).show()
Let's pull out Fantasy by 50px too.
Chord(matrix, names, pull=[0, 50, 0, 0, 50, 0]).show()
How about everything pulled out to different positions?
Chord(matrix, names, pull=[0, 20, 40, 60, 80, 100]).show()
Highlighting groups
Let's highlight Thriller and Action as if they are related somehow.
Chord(
matrix,
names,
colors=["red", "blue", "blue", "blue", "blue", "red"],
pull=[20, 0, 0, 0, 0, 20],
).show()
Pushing instead of pulling
To push instead of pull, you can use negative numbers.
Chord(
matrix,
names,
pull=[0, 0, 0, 0, -30, 0],
).show()
