Stacked Step Area Chart in React Charts

Stacked Step Area
To render a stacked step 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
typeasStackingStepAreain your chart configuration. This indicates that the data should be represented as a stacked step area chart, which is a combination of a stacked area chart and a step area chart. It connects the data points with vertical and horizontal lines, creating a step like appearance. -
Inject the StackingStepAreaSeries module: Inject
StackingStepAreaSeriesmodule into theservices. This step is essential, as it ensures that the necessary functionalities for rendering stacked step 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.

];Stack labels customization
Stack labels have various properties for customization to enhance the visual based on your requirements:
-
visible- Specifies whether stack labels are visible. Setting to true will display the labels. Default is false. -
fill- Defines the background color of the stack labels. Accepts valid CSS color strings (hex, RGBA, etc.). Default is transparent. -
format- Formats the text displayed in the stack labels. Supports placeholders like {value}. Default is null. -
angle- Specifies the rotation angle for stack labels in degrees. Default is 0. -
rx- Defines the rounded corner radius along the X-axis (horizontal direction) for the stack label background. Default is 5. -
ry- Defines the rounded corner radius along the Y-axis (vertical direction) for the stack label background. Default is 5. -
margin- Configures the margin around the stack label (left, right, top, and bottom). -
border- Configures the appearance of the stack label’s border. -
font- Customizes the stack label text, including font size, color, style, weight, and family.
