templateUrl: "./bar-chart.component.html",
styleUrls: ["./bar-chart.component.css"]
})
export class BarChartComponent implements OnInit {
readonly echartsExtentions: any[];
echartsOptions: object = {};

constructor() {
this.echartsExtentions = [BarChart, TooltipComponent, GridComponent, LegendComponent];
}

ngOnInit() {
this.echartsOptions = {
