Stacked Line in React Chart component

1 Apr 202524 minutes to read

Stacked Line

To render a stacked line 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:

  1. Set the series type: Define the series type as StackingLine in your chart configuration. This indicates that the data should be represented as a stacked line chart, allowing multiple data series to be stacked on top of each other. This makes it easier to compare the contribution of each series to the total over a specific period.

  2. Inject the StackingLineSeries module: Inject StackingLineSeries module into the services. This step is essential, as it ensures that the necessary functionalities for rendering stacked line series are available in your chart.

function App() {
    const marker = { visible: true, width: 10, height: 10, border: { width: 2, color: '#F8AB1D' } };
    return <ChartComponent id='charts' primaryXAxis={{ interval: 1, valueType: 'Category' }} primaryYAxis={{ title: 'Expense', minimum: 0, maximum: 400, interval: 100, labelFormat: '${value}' }}>
         <Inject services={[StackingLineSeries, Legend, Tooltip, DataLabel, Category]}/>

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.

Empty points

Data points with null or undefined values are considered empty. Empty data points are ignored and not plotted on the chart.

Mode

Use the mode property to define how empty or missing data points are handled in the series. The default mode for empty points is Gap.

Events

Series render

The seriesRender event allows you to customize series properties, such as data, fill, and name, before they are rendered on the chart.

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.
