The TreeMap control supports data binding using the dataSource property.
The dataSource property accepts collection values as input. For example, a list of objects can be provided as input. Data can be given as either flat or hierarchical collection to the dataSource property.
The following code shows, how to bind a flat collection as data source to the TreeMap control.
import { Component } from '@angular/core';
@Component({
selector: 'app-container',
template: `<ejs-treemap id='container' style='display: block;' height='350px' [dataSource]='data' weightValuePath='GDP'
[leafItemSettings]='leafItemSettings'>
</ejs-treemap>`
})
export class AppComponent {
public data: object[] = [
{State:"United States", GDP:17946, percentage:11.08, Rank:1},
{State:"China", GDP:10866, percentage: 28.42, Rank:2},
{State:"Japan", GDP:4123, percentage:-30.78, Rank:3},
{State:"Germany", GDP:3355, percentage:-5.19, Rank:4},
{State:"United Kingdom", GDP:2848, percentage:8.28, Rank:5},
{State:"France", GDP:2421, percentage:-9.69, Rank:6},
{State:"India", GDP:2073, percentage:13.65, Rank:7},
{State:"Italy", GDP:1814, percentage:-12.45, Rank:8},
{State:"Brazil", GDP:1774, percentage:-27.88, Rank:9},
{State:"Canada", GDP:1550, percentage:-15.02, Rank:10}
];
public leafItemSettings: object = {
labelPath: 'State'
};
