High Low Chart in React Charts

High Low

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:

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.
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.
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.

Series customization

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

Fill

The fill property determines the color applied to the series.

    { x: 'Sep',  low: 60, high: 155 }, { x: 'Oct',  low: 60, high: 180 },
    { 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 controls the transparency of the fill and affects how the series blends with background or overlapping series.

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.
