To render a step area series, use series type as StepArea
and inject StepAreaSeries module using Chart.Inject(StepAreaSeries) method.
import { Chart, StepAreaSeries } from '@syncfusion/ej2-charts';
import { numData } from './datasource.ts';
Chart.Inject(StepAreaSeries);
let chart: Chart = new Chart({
series:[{
dataSource: numData,
xName: 'x', yName: 'y',
type: 'StepArea'
}],
}, '#element');<!DOCTYPE html>
