Changing the Colours and Icons

Preamble

In [1]:
from plotapi import PieFight

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

Introduction

Let's take a look at how we can change the colours and icons for nodes in our Pie Fight diagram.

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

Dataset

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

In [2]:
samples = [
    {"order": 0, "name": "Sankey", "value": 10},
    {"order": 0, "name": "Terminus", "value": 12},
    {"order": 0, "name": "Chord", "value": 8},
    {"order": 0, "name": "Bar Fight", "value": 9},
    {"order": 0, "name": "Pie Fight", "value": 12},

    {"order": 1, "name": "Sankey", "value": 18},
    {"order": 1, "name": "Terminus", "value": 24},
    {"order": 1, "name": "Chord", "value": 22},
    {"order": 1, "name": "Bar Fight", "value": 14},
    {"order": 1, "name": "Pie Fight", "value": 17},

    {"order": 2, "name": "Sankey", "value": 24},
    {"order": 2, "name": "Terminus", "value": 40},
    {"order": 2, "name": "Chord", "value": 32},
    {"order": 2, "name": "Bar Fight", "value": 19},
    {"order": 2, "name": "Pie Fight", "value": 42},

    {"order": 3, "name": "Sankey", "value": 32},
    {"order": 3, "name": "Terminus", "value": 62},
    {"order": 3, "name": "Chord", "value": 40},
    {"order": 3, "name": "Bar Fight", "value": 25},
    {"order": 3, "name": "Pie Fight", "value": 64},

    {"order": 4, "name": "Sankey", "value": 38},
    {"order": 4, "name": "Terminus", "value": 75},
    {"order": 4, "name": "Chord", "value": 55},
    {"order": 4, "name": "Bar Fight", "value": 45},
    {"order": 4, "name": "Pie Fight", "value": 120},
]

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 pie chart segment.
  • value, the value of the segment at the associated point in time.

Next, we'll start customising the segments, or nodes, that will represent our data over time. Plotapi Pie Fight expects a list of dictionary items to configure each node.

In [5]:
nodes = [
    {
        "name": "Sankey",
        "color": "#ffd166", 
        "icon": "https://datacrayon.com/datasets/pokemon_img/003.png"
    },
    {
        "name": "Terminus",
        "color": "#06d6a0", 
        "icon": "https://datacrayon.com/datasets/pokemon_img/004.png"
    },
    {
        "name": "Chord",
        "color": "#118ab2", 
        "icon": "https://datacrayon.com/datasets/pokemon_img/025.png"
    },
    {
        "name": "Bar Fight",
        "color": "#073b4c", 
        "icon": "https://datacrayon.com/datasets/pokemon_img/151.png"
    },
    {
        "name": "Pie Fight",
        "color": "#ef476f", 
        "icon": "https://datacrayon.com/datasets/pokemon_img/232.png"
    }
]

We can see that each dictionary item has three properties:

  • name, the name of the item, which corresponds to names specified in the samples definitions above.
  • color, the desired colour of the pie chart segment (CSS colour e.g. "#073b4c" or "red").
  • icon, the location of the image to use for the icon.

Visualisation

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!

In [6]:
PieFight(samples,
         nodes=nodes).show()
