Percentage Stacked Column Chart

Application Scenario

Each layer of the column represents the percentage of each category's data to the total data in the group. Each series is stacked according to its percentage, helping you directly view each series' proportion. The following figure shows the comparison and change of the public attitude to corporal punishment of children from 1986 to 2016.

Basic Requirement

The following table shows basic requirements of a percentage stacked column chart.

Chart Feature

Advantage: The chart can clearly display the proportion of different indicators in each dimension to help you compare the data volumes of different dimensions.

Disadvantage: If too many indicators are stacked, you may struggle to distinguish and compare the data, and compare the same dimension's data in different categories.
