Hilo Charts in React Chart component

Hilo

To render a hilo 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 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, you need to specify both the high and low values. The high value represents the maximum price, while the low value represents the minimum price of the stock.

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';

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>

Series customization

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

Fill

The fill property determines the color applied to the series.

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>
    </ChartComponent>;
}
;
export default App;

    HiloSeries, Category, Tooltip, ILoadedEventArgs, Zoom,
    Crosshair, ChartTheme }
from'@syncfusion/ej2-react-charts';

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

          high='high' fill='blue'>
        </SeriesDirective>

    { x: 'May',  low: 27, high: 80 },  { x: 'June', low: 84, high: 130 },
    { x: 'July', low: 77, high: 150 }, { x: 'Aug',  low: 54, high: 125 },
    { x: 'Sep',  low: 60, high: 155 }, { x: 'Oct',  low: 60, high: 180 },
    { x: 'Nov',  low: 88, high: 180 }, { x: 'Dec',  low: 84, high: 230 }
];
export let chartData: Object[] = [
    { x: 'Jan',  low: 87, high: 200 }, { x: 'Feb',  low: 45, high: 135 },
    { x: 'Mar',  low: 19, high: 85 },  { x: 'Apr',  low: 31, high: 108 },
    { x: 'May',  low: 27, high: 80 },  { x: 'June', low: 84, high: 130 },

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

The fill property can be used to apply a gradient color to the hilo 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 specifies the transparency level of the fill. Adjusting this property allows you to control how opaque or transparent the fill color of the series appears.

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.

    const legendSettings = { visible: false };
    const seriesRender = (args) => {
      args.fill = '#ff6347';
