Preamble¶
from plotapi import HeatMap HeatMap.set_license("your username", "your license key")
Introduction¶
Our first Plotapi Heat Map Diagram! As we can see, we have set our license details in the preamble with HeatMap.set_license()
Dataset¶
Plotapi Heat Map expects a matrix (list[list[float]]
) as input.
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], ] row_names = ["Action", "Adventure", "Comedy", "Drama", "Fantasy", "Thriller"] col_names = ["Action", "Adventure", "Comedy", "Drama", "Fantasy", "Thriller"]
Optionally, we can include a list of row_names
and col_names
(list[str]
).
It may look more clear if we present this as a table with the columns and indices labelled. This is entirely optional.
import pandas as pd pd.DataFrame(matrix, columns=col_names, index=row_names)
Action Adventure Comedy Drama Fantasy Thriller Action 0 5 6 4 7 4 Adventure 5 0 5 4 6 5 Comedy 6 5 0 4 5 5 Drama 4 4 4 0 5 5 Fantasy 7 6 5 5 0 4 Thriller 4 5 5 5 4 0
Visualisation¶
Creating our first Heat Map Diagram is as easy as calling Plotapi with our inputs.
Here we're using .show()
which outputs to a Jupyter Notebook cell, however, we may want to output to a 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!
HeatMap(matrix, row_names=row_names, col_names=col_names).show()
Plotapi - Chord Diagram
If we omit the row_names
and col_names
, Plotapi will auto-generate the names for us.
HeatMap(matrix).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. and the Plotapi Gallery.
