High Low Chart in React Chart

20 Aug 202624 minutes to read

High Low

The Hilo series is used to visualize the high and low values for each data point, often illustrating price movements.

To render a Hilo series in your chart, follow these steps:

  1. Set the series type: Define the series type as Hilo in your chart configuration. This indicates that the data should be represented as a hilo chart, which shows the high and low values for each data point, illustrating price movements in stocks and providing a clear visualization of price ranges.

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

  3. Provide high and low values: The Hilo series requires two y-values for each data point. Specify both the high and low values on the data record — high represents the maximum value and low represents the minimum value.

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, HiloSeries, Category, Tooltip, Zoom, Crosshair } from '@syncfusion/ej2-react-charts';
import { chartData } from './datasource';

function App() {
    const primaryxAxis = { valueType: 'Category', title: 'Months' };
    const primaryyAxis = { labelFormat: '{value}mm', edgeLabelPlacement: 'Shift', title: 'Rainfall' };
    const style = { textAlign: "center" };
    const legendSettings = { visible: false };
    return <ChartComponent id='charts' style={style} primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} legendSettings={legendSettings} title='Maximum and Minimum Rainfall'>
      <Inject services={[HiloSeries, Tooltip, Category, Crosshair, Zoom]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={chartData} xName='x' yName='low' name='India' type='Hilo' low='low' high='high'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

import * as ReactDOM from "react-dom";
import { AxisModel, ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, LegendSettingsModel,

];

Series customization

The following properties can be used to customize the Hilo series.

Solid fill

The fill property determines the color applied to the series, for example:

<SeriesDirective fill="red" />

import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, HiloSeries, Category, Tooltip, Zoom, Crosshair } from '@syncfusion/ej2-react-charts';
import { chartData } from './datasource';

function App() {
    const primaryxAxis = { valueType: 'Category', title: 'Months' };
    const primaryyAxis = { labelFormat: '{value}mm', edgeLabelPlacement: 'Shift', title: 'Rainfall' };
    const style = { textAlign: "center" };
    const legendSettings = { visible: false };
    return <ChartComponent id='charts' style={style} primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} legendSettings={legendSettings} title='Maximum and Minimum Rainfall'>
      <Inject services={[HiloSeries, Tooltip, Category, Crosshair, Zoom]}/>
      <SeriesCollectionDirective>
        <SeriesDirective dataSource={chartData} xName='x' yName='low' name='India' type='Hilo' low='low' high='high' fill='blue'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>;
}
;
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));
import * as React from "react";
import * as ReactDOM from "react-dom";
import { AxisModel, ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject,LegendSettingsModel,
    HiloSeries, Category, Tooltip, ILoadedEventArgs, Zoom,
    Crosshair, ChartTheme }
from'@syncfusion/ej2-react-charts';
import { chartData } from './datasource';

function App() {
  const primaryxAxis: AxisModel = { valueType: 'Category', title: 'Months' };
  const primaryyAxis: AxisModel = { labelFormat: '{value}mm', edgeLabelPlacement: 'Shift', title: 'Rainfall' };
  const style: any = { textAlign: "center" };

      <SeriesCollectionDirective>
        <SeriesDirective dataSource={chartData} xName='x' yName='low' name='India' type='Hilo' low='low'
          high='high' fill='blue'>
        </SeriesDirective>
      </SeriesCollectionDirective>
    </ChartComponent>

};
export default App;
ReactDOM.render(<App />, document.getElementById("charts"));

    { x: 'Nov',  low: 88, high: 180 }, { x: 'Dec',  low: 84, high: 230 }
];

Gradient fill

The fill property can also apply a gradient color across the series (e.g., url(#gradient) referencing an SVG gradient defined elsewhere in the component).

    const style = { textAlign: "center" };
    const legendSettings = { visible: false };
    return <ChartComponent id='charts' style={style} primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} legendSettings={legendSettings} title='Maximum and Minimum Rainfall'>

    { x: 'Nov',  low: 88, high: 180 }, { x: 'Dec',  low: 84, high: 230 }
];

Opacity

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

];

Empty points

A Hilo data point is considered empty when either its high or low value is null, undefined, or NaN. By default (Gap mode) the empty point is skipped and leaves a gap on the chart; the mode and fill properties of emptyPointSettings let you override this behavior.

Mode

Use the mode property to control handling of empty points. Available modes are Gap (leave a break, the default), Drop (ignores the empty point during rendering), Zero (plot as zero), and Average (plot as the average of neighboring points).

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.

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

function App() {
    const primaryxAxis = { valueType: 'Category', title: 'Months' };
    const primaryyAxis = { labelFormat: '{value}mm', edgeLabelPlacement: 'Shift', title: 'Rainfall' };
    const style = { textAlign: "center" };
    const legendSettings = { visible: false };
    const seriesRender = (args) => {
      args.fill = '#ff6347';
    };
    return <ChartComponent id='charts' style={style} primaryXAxis={primaryxAxis} primaryYAxis={primaryyAxis} legendSettings={legendSettings} title='Maximum and Minimum Rainfall' seriesRender={seriesRender}>

Point render

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

    const primaryyAxis = { labelFormat: '{value}mm', edgeLabelPlacement: 'Shift', title: 'Rainfall' };
    const style = { textAlign: "center" };
    const legendSettings = { visible: false };
    const pointRender = (args) => {
      if (args.point.index % 2 !== 0) {
        args.fill = '#ff6347';
    }
    else {
        args.fill = '#009cb8';
    }
    };
