ng2-charts update labels and data

Question

I\'m trying to create dynamically a chart using ng2-chart, I get information from an angular 2 service, when I change only labels of chart it works and when I change data on

Answer 1

Using BaseChartDirective i did chart update and it served the purpose. Sample below:

import { BaseChartDirective } from 'ng2-charts/ng2-charts';

inside the class add as below

@ViewChild(BaseChartDirective) chart: BaseChartDirective;

While you have the values to be changed, add as below

 this.chart.ngOnChanges({});
