Preamble 

from plotapi import LineFight

LineFight.set_license("your username", "your license key")

Introduction

Our first Plotapi Line Fight Diagram!

Plotapi Line Fight is a beautiful and feature rich take on the popular Line Chart Race. As we can see, we have set our license details in the preamble with LineFight.set_license().

Dataset

Plotapi Line Fight expects at minimum a list of dictionary items, these will define the value of our lines over time.

samples = [
    {"order": 0, "name": "Sankey", "value": 10},
    {"order": 0, "name": "Terminus", "value": 10},
    {"order": 0, "name": "Chord", "value": 40},
    {"order": 0, "name": "Bar Fight", "value": 90},
    {"order": 0, "name": "Pie Fight", "value": 70},

    {"order": 1, "name": "Sankey", "value": 30},
    {"order": 1, "name": "Terminus", "value": 20},
    {"order": 1, "name": "Chord", "value": 40},
    {"order": 1, "name": "Bar Fight", "value": 120},
    {"order": 1, "name": "Pie Fight", "value": 55},

    {"order": 2, "name": "Sankey", "value": 35},
    {"order": 2, "name": "Terminus", "value": 45},
    {"order": 2, "name": "Chord", "value": 60},
    {"order": 2, "name": "Bar Fight", "value": 85},
    {"order": 2, "name": "Pie Fight", "value": 100},

    {"order": 3, "name": "Sankey", "value": 25},
    {"order": 3, "name": "Terminus", "value": 60},
    {"order": 3, "name": "Chord", "value": 90},
    {"order": 3, "name": "Bar Fight", "value": 50},
    {"order": 3, "name": "Pie Fight", "value": 105},

    {"order": 4, "name": "Sankey", "value": 60},
    {"order": 4, "name": "Terminus", "value": 80},
    {"order": 4, "name": "Chord", "value": 120},
    {"order": 4, "name": "Bar Fight", "value": 30},
    {"order": 4, "name": "Pie Fight", "value": 95},
]

We can see that each dictionary item has three properties:

  • order which determines with time period this item belongs to. This should be numerical, but can be formatted e.g. as dates.
  • name the name of the item, and the text that appears on the lines.
  • value the value of the lines at the associated point in time.

Visualisation

Creating our first Line Fight Diagram is as easy as calling Plotapi with our one input.

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!

Here we can see the default behaviour of Plotapi Line Fight.

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.
