Range step area Chart in React Chart component

Range step area

To render a range step 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:

Set the series type: Define the series type as RangeStepArea in your chart configuration. This indicates that the data should be represented as a range step area chart, which is ideal for displaying data points as a range with high and low values. It connects these points with vertical and horizontal lines, creating a step like appearance.
Inject the RangeStepAreaSeries module: Inject RangeStepArea series in to the service. This step is essential, as it ensures that the necessary functionalities for rendering range step area series are available in your chart.
Provide high and low values: The RangeStepArea 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 range, while the low value represents the minimum range for each data point. These values define the upper and lower boundaries of the area for each point on the chart.

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 range step 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 range step 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 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.
