Multi-dimensional Sankey Chart Usage

Background Introduction

Sankey chart, also known as Sankey energy flow chart, or Sankey energy balance chart. It is a specific type of flow chart where the width of the extending branches corresponds to the size of the data flow. The most obvious feature of Sankey charts is that the total width of the branches at the beginning and end are equal, that is, the sum of the widths of all main branches should be equal to the sum of the widths of all outgoing branches, maintaining energy balance.

The multi-dimensional Sankey chart functionality is available in version 3.8.0 and later. Historical versions were two-dimensional Sankey charts, which will be discontinued after December 2021 and no longer maintained.

Production Method

Create a new card, select "Other Types - Multi-dimensional Sankey Chart". Sankey charts need to drag in at least three fields, that is, two dimension fields and one numerical field. Multi-dimensional Sankey charts support up to 5 dimension fields.

(Before making the card, it is recommended to process the data with ETL first)
