Step line in React Chart component
14 Oct 202424 minutes to read
Step line
To render a step line 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
asStepLine
in your chart configuration. This indicates that the data should be represented as a step line chart, which connects data points with horizontal and vertical lines, creating a staircase effect. This type is ideal for displaying data that changes at distinct points. -
Inject the StepLineSeries module: Inject
StepLineSeries
module into theservices
. This step is essential, as it ensures that the necessary functionalities for rendering step line series are available in your chart.
import * as React from "react";
import * as ReactDOM from "react-dom";
import { ChartComponent, SeriesCollectionDirective, SeriesDirective, Inject, Legend, Category, Tooltip, DataLabel, StepLineSeries } from '@syncfusion/ej2-react-charts';
import { steplineData } from './datasource';
function App() {
const marker = { visible: true, width: 10, height: 10, border: { width: 2, color: '#F8AB1D' } };
return <ChartComponent id='charts'>
<Inject services={[StepLineSeries, Legend, Tooltip, DataLabel, Category]}/>

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
and yName
properties.

Series customization
The following properties can be used to customize the step line
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 step line 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.

No risers
You can eliminate the vertical lines between points by using the ‘noRisers’property in a series. This approach is useful for highlighting trends without the distraction of risers.

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
.
