Stacked Area Chart in React Chart

17 Aug 202624 minutes to read

Stacked area

Follow these steps to render a stacked area series, which stacks multiple area series on top of each other to show each one’s contribution to a total over time or across categories. To display proportional totals (100%), use StackingArea100 with the same configuration.

Set the series type: Set the series type to StackingArea in the series configuration.
Inject the StackingAreaSeries module: Add StackingAreaSeries to the services array of the Inject component inside ChartComponent. This registers the functionality required to render a stacked area series.

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 example below uses the same StackingArea configuration shown above with a typical JSON dataset and the xName/yName mapping applied.

Series customization

Customize the stacked area series appearance with the following properties. Defaults are taken from the standard Series model.

Property	Type	Default	Description
`fill`	string	`null`	Color applied to the series. Accepts a CSS color or a gradient reference.
`opacity`	number	`1`	Transparency of the fill (0 to 1).
`border`	`BorderModel`	`null`	Border settings: `width`, `color`, and `dashArray`.

Solid fill

The fill property determines the color applied to the series.

Empty points

Data points with null or undefined values are considered empty. By default (mode: 'Gap'), empty points leave a gap in the stack; the mode property on emptyPointSettings lets you change how they are handled.

Mode

Use the mode property to control handling of empty points. Available modes: Gap, Drop, Zero, Average. The default mode is Gap.

Stack labels

The stack labels in stacked area, stacked bar, and stacked column charts display cumulative total values for stack segments as inline data labels. If a stacked point has negative values, the stack labels are displayed below the point. Stack labels are independent of the dataLabel settings within each series.

Stack labels customization

Stack labels have various properties for customization to enhance the visual based on your requirements:

Property	Type	Default	Description
`visible`	boolean	`false`	Specifies whether stack labels are visible. Setting to `true` displays the labels.
`fill`	string	`transparent`	Background color of the stack labels. Accepts valid CSS color strings (hex, RGBA, etc.).
`format`	string	`null`	Format string for the label text. Supports placeholders such as `{value}`.
`angle`	number	`0`	Rotation angle for stack labels in degrees.
`rx`	number	`5`	Rounded corner radius along the X-axis for the stack label background.
`ry`	number	`5`	Rounded corner radius along the Y-axis for the stack label background.
`margin`	`MarginModel`	`null`	Margin around the stack label (`left`, `right`, `top`, `bottom`).
`border`	`BorderModel`	`null`	Border appearance of the stack label.
`font`	`StackLabelsFontModel`	`null`	Font customization (`size`, `color`, `fontStyle`, `fontWeight`, `fontFamily`).

Events

Series render

The seriesRender event fires before each series is rendered and lets you modify series properties such as data, fill, or name. For a stacked area series, use it to vary per-series fill or to swap data sources between renders.

Point render

The pointRender event fires before each data point is drawn, letting you customize per-point marker shape, border, or fill. For a stacked area series, use it to highlight specific points or apply conditional formatting.
