index.ts
index.html
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { numData } from './datasource.ts';
Chart.Inject(BarSeries, Category);

let chart: Chart = new Chart({
   series:[{
        dataSource: numData,
        xName: 'x', yName: 'y',
        // Series type as bar series
        type: 'Bar'

index.ts
index.html
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
import { numData } from './datasource.ts';
Chart.Inject(BarSeries, Category);

let chart: Chart = new Chart({
   series:[{
        dataSource: numData,
        xName: 'x', yName: 'y',
        // Series type as bar series
        type: 'Bar'
    },
    {
        dataSource: numData,
        xName: 'x',
        yName: 'y1',
        columnSpacing: 0.5,
        columnWidth: 0.75,
        // Series type as bar series
        type: 'Bar',

Grouped bar

You can use the groupName property to group the data points in the bar type charts. Data points with same group name are grouped together.

index.ts
index.html
import { Chart, BarSeries, Category } from '@syncfusion/ej2-charts';
Chart.Inject(BarSeries, Category);

let chart: Chart = new Chart({
         primaryXAxis: {
            valueType: 'Category',
        },
        series: [
            {
                type: 'Bar', xName: 'x', width: 2, yName: 'y', groupName: 'USA', columnWidth: 0.7,
                dataSource: [{ x: '2012', y: 104 }, { x: '2016', y: 121 }, { x: '2020', y: 113 }], columnSpacing: 0.1,
            },
            {
                type: 'Bar', xName: 'x', width: 2, yName: 'y', groupName: 'USA', columnWidth: 0.5,
                dataSource: [{ x: '2012', y: 46 }, { x: '2016', y: 46 }, { x: '2020', y: 39 }], columnSpacing: 0.1,
            },
            {
                type: 'Bar', xName: 'x', width: 2, yName: 'y', groupName: 'UK', columnWidth: 0.7,
                dataSource: [{ x: '2012', y: 65 }, { x: '2016', y: 67 },{ x: '2020', y: 65 }], columnSpacing: 0.1,
            },
            {
                type: 'Bar', xName: 'x', width: 2, yName: 'y', groupName: 'UK', columnWidth: 0.5,
                dataSource: [{ x: '2012', y: 29 }, { x: '2016', y: 27 },{ x: '2020', y: 22 }], columnSpacing: 0.1,
            },

    series: [{
        dataSource: cylindricalData,
        xName: 'x', yName: 'y',
