Stacked Column Chart
A stacked column chart allows part-to-whole comparisons over time, or across categories. In a stacked column chart, data series are stacked one on top of the other in vertical columns.
Stacked column charts can show change over time because it’s easy to compare total column lengths. However, it can difficult to compare the relative size of the components that make up each bar. As categories or data series are added, stacked column charts quickly become complicated.
This chart shows the wildlife population in an area of the year. It is broken down into 3 animals that are stacked, one on top of the other. Stacked column charts work best when the number of data series and categories is limited.
1. How to add and configure a stacked column chart.
The following steps explain the data configuration of the stacked column chart:
- Drag and drop the stacked column chart icon from the toolbox into the design panel.
- Resize the widget as required.
- Select your chart and in the properties section, you can name the chart and change any settings you wish.
- You can then select assign data and select your data source.
Please note that before adding a component you will need to define a data source.
- Drag and drop the relevant columns into the value, column and row section.
