Spline Range Area Chart in React Charts

3 Feb 202624 minutes to read

Spline Range Area

To render a spline range 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:

  1. Set the series type: Define the series type as SplineRangeArea in your chart configuration. This indicates that the data should be represented as a spline range area chart, which is ideal for visualizing continuous data points as a set of splines that vary between high and low values over intervals of time and across different categories.

  2. Inject the SplineRangeAreaSeries module: Inject SplineRangeAreaSeries module into the services. This step is essential, as it ensures that the necessary functionalities for rendering spline range area series are available in your chart.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Category, SplineRangeAreaSeries } from '@syncfusion/ej2-react-charts';
import { splineRangeData } from './datasource';
function App() {
    const primaryxAxis = {
        valueType: 'Category',
        edgeLabelPlacement: 'Shift',
        majorGridLines: { width: 0 }
    };
    const primaryyAxis = {
        labelFormat: '{value}˚C',
        lineStyle: { width: 0 },
        minimum: 0, maximum: 40,
        majorTickLines: { width: 0 }
    };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} title='Monthly Temperature Range'>
      <Inject services={[SplineRangeAreaSeries, Category]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={splineRangeData} xName='x' high='high' low='low' name='England' type='SplineRangeArea'>
        </SeriesDirective>
        <SeriesDirective dataSource={splineRangeData} xName='x' high='high1' low='low1' name='India' type='SplineRangeArea'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}

    lineStyle: { width: 0 },
    minimum: 0, maximum: 40,
    majorTickLines: { width: 0 }
  };

      </SeriesCollectionDirective>
    </ChartComponent>
  
};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
export let splineRangeData = [
    { x: 'Jan', high: 14, low: 4,  high1: 29, low1: 19 },

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, high, and low properties.

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Category, SplineRangeAreaSeries } from '@syncfusion/ej2-react-charts';

function App() {
    const primaryxAxis = {
        valueType: 'Category',
        edgeLabelPlacement: 'Shift',
        majorGridLines: { width: 0 }
    };
    const primaryyAxis = {
        labelFormat: '{value}˚C',
        lineStyle: { width: 0 },
        minimum: 0, maximum: 40,
        majorTickLines: { width: 0 }
    };
    return <ChartComponent id='charts' primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} title='Monthly Temperature Range'>

Series customization

The following properties can be used to customize the spline range area series.

Fill

The fill property determines the color applied to the series.

The fill property can be used to apply a gradient color to the spline range 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.

Opacity

The opacity property controls the transparency of the fill and affects how the series blends with background or overlapping series.

    };
    const primaryyAxis = {
        labelFormat: '{value}˚C',
        lineStyle: { width: 0 },
        minimum: 0, maximum: 40,

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

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.

Point render

The pointRender event provides a hook to customize each data point (for example, marker shape, border, or fill) before it is drawn. Use this to apply per-point styling rules or conditional formatting.

    };
    const primaryyAxis = {
        labelFormat: '{value}˚C',
        lineStyle: { width: 0 },
        minimum: 0, maximum: 40,
        majorTickLines: { width: 0 }
    };
    const marker = { visible: true };
    const pointRender = (args) => {
      if (args.point.index % 2 !== 0) {
        args.fill = '#ff6347';
    }
    else {
        args.fill = '#009cb8';
