Aster plots are used to display two metrics per slice in a pie chart visualisation. Each pie slice has a length and width component.
The first measure, the length, represents the score of each slice, is the value extending from the centre of the pie outwards to the edge (0 is the centre and the outer circle length is defaulted to max value of all scores).
The second measure, the width, represents the weight of each slice, which gets used to arrive at a weighted mean score of the length scores in the centre. This score can also be overriden by entering a custom keyword search to use a row level value's length in place of the weighted mean score. See example below.
This implementation for Looker was built based on the Ben Best’s Aster Plot in D3 Block.
