27 Sep 20236 minutes to read

You can visualize the data that returned by grid in chart.

To visualize the data in chart, follow the given steps:

Step 1:

Initialize the grid with datasource.

Step 2:

By using the grid’s actionComplete event and getCurrentViewRecords method, you can get the current page records.
By using the grid’s databound event, you can update the current page records into the chart’s datasource and visualize the grid data in chart.

import { Component, OnInit, ViewChild } from '@angular/core';
import { IDragCompleteEventArgs, ChartComponent } from '@syncfusion/ej2-angular-charts';
import { GridComponent, ActionEventArgs } from '@syncfusion/ej2-angular-grids';
import { Query, DataManager } from '@syncfusion/ej2-data';
import { orderData } from './datasource';
@Component({
    selector: 'app-container',
    template: `<ejs-grid #grid [dataSource]='data' [allowPaging]="true" [pageSettings]='pageSettings' (dataBound)='dataBound()'
    (actionComplete)='actionComplete($event)'>
                 <e-columns>
                    <e-column field='OrderDate' headerText='Order Date' width=130 format='yMd' textAlign='right'></e-column>
                    <e-column field='Freight' width=120 format='C2' textAlign='right'></e-column>
                </e-columns>
