100% Stacked Area Chart in React Charts

3 Feb 202624 minutes to read

100% Stacked Area

To render a 100% stacked area series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

Set the series type: Define the series type as StackingArea100 in your chart configuration. This indicates that the data should be represented as a 100% stacked area chart, where the cumulative values for each data point are expressed as a percentage of the total. This ensures that the sum of all series at each point is always 100%.
Inject the StackingAreaSeries module: Inject StackingAreaSeries module into the services. This step is essential, as it ensures that the necessary functionalities for rendering 100% stacked area series are available in your chart.

Binding data with series

You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName and yName properties.

The fill property can be used to apply a gradient color to the 100% stacked area series. By configuring this property with gradient values, you can create a visually appealing effect in which the color transitions smoothly from one shade to another.

Events

Series render

The seriesRender event enables modification of series properties (for example, data, fill, or name) immediately before rendering. Use this event to adjust series appearance or to dynamically swap data sources.
