How to Bind Dynamic Data to the E-series of a Chart?

Description

This article explains how to dynamically bind data to the e-series elements in a chart component using Angular.

Solution

To dynamically bind data in an Angular Chart Component, you can use Angular’s ngFor directive. This structural directive allows you to iterate over an array and generate a series for each data set dynamically. Each object in the array corresponds to a series, and its data can be rendered directly within the chart using e-series.

Code Snippet

app.component.html

           <e-series-collection>
               <e-series *ngFor="let row of dataTotal" [dataSource]='row.data' xName='x' yName='y'> </e-series>
           </e-series-collection>

app.component.ts

export class AppComponent {
   public dataTotal: Object[] = [
       {
         data : [
           { x: new Date(1975, 0, 1), y: 16 },
           { x: new Date(1980, 0, 1), y: 12.5 },
           { x: new Date(1985, 0, 1), y: 19 },
           { x: new Date(1990, 0, 1), y: 14.4 },
           { x: new Date(1995, 0, 1), y: 11.5 },
           { x: new Date(2000, 0, 1), y: 14 },
           { x: new Date(2005, 0, 1), y: 10 },
           { x: new Date(2010, 0, 1), y: 16 }
         ],
         seriesName: 'China'
       },
       {
       data : [
           { x: new Date(1975, 0, 1), y: 10 },
           { x: new Date(1980, 0, 1), y: 7.5 },
           { x: new Date(1985, 0, 1), y: 11 },
           { x: new Date(1990, 0, 1), y: 7 },
           { x: new Date(1995, 0, 1), y: 8 }, 
           { x: new Date(2000, 0, 1), y: 6 },
           { x: new Date(2005, 0, 1), y: 3.5 },
           { x: new Date(2010, 0, 1), y: 7 }
       ],
       seriesName:'Australia'
     }
     ];
  }
