@Component({
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'[tooltip]='tooltip'>
        <e-series-collection>
            <e-series [dataSource]='chartData' type='Column' xName='x' yName='y' name='Product X' [marker]='marker'></e-series>
            <e-series [dataSource]='chartData' type='Column' xName='x' yName='y1' name='Product Y ' [marker]='marker'></e-series>
        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public tooltip?: Object;
    public marker?: Object;
    public primaryYAxis?: Object;
    ngOnInit(): void {
        this.chartData = [
                { x: 1900, y: 4, y1: 2.6, y2: 2.8 }, { x: 1920, y: 3.0, y1: 2.8, y2: 2.5 },
                { x: 1940, y: 3.8, y1: 2.6, y2: 2.8 }, { x: 1960, y: 3.4, y1: 3, y2: 3.2 },
                { x: 1980, y: 3.2, y1: 3.6, y2: 2.9 }, { x: 2000, y: 3.9, y1: 3, y2: 2 }
        ];
        this.primaryXAxis = {
            title: 'Year',
            edgeLabelPlacement: 'Shift'
        };
        this.primaryYAxis = {
           title: 'Sales Amount in Millions',
           labelFormat: 'c'
        };
        this.tooltip = {
            enable: true, format: '${series.name} <br>${point.x} : ${point.y}'
        };
        this.marker = {
            dataLabel: {
                visible: true
            }
        };
        this.title = 'Average Sales Comparison';
    }
