Internationalization in Angular TreeMap component

09 Jun 2021 / 5 minutes to read

The tree map control supports internationalization for the following elements:

Data label
Tooltip

For more information about number and date formatter, refer to internationalization.

Globalization

Globalization is the process of designing and developing a component that works in different cultures/locales. Internationalization library is used to globalize number, date, and time values in the tree map control using the [format] property in the treemap model.

Numeric format

In the following code example, tooltip is globalized to Deutsch culture.

import { Component } from '@angular/core';

@Component({
selector: 'app-container',
template: `<ejs-treemap id='container' style='display: block;' [dataSource]='data' weightValuePath='GDP' format='c' useGroupingSeparator= 'true'
   >
</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}
];
}

Right-to-left rendering

The TreeMap control supports right-to-left rendering for all its elements such as nodes, tooltip, data labels, and legends.

Legend with Rtl support

If you set the enableRtl property to true, then the legend icon will be rendered on the right and the legend text will be rendered on the left of the legend icon.

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

If the enableRtl property is set to true, the tooltip data will be rendered in reverse direction.

The following example shows the format of the tooltip.

Treemap Item Rendering Direction

By default, the direction of tree map item is TopLeftBottomRight. You can customize the rendering direction of the tree map item by setting the renderDirection property. The TreeMap can be rendered in the following four different directions. TopLeftBottomRight TopRightBottomLeft BottomRightTopLeft BottomLeftTopRight

The following example demonstrate how to render the treemap in the RTL direction with TopLeftBottomRight.
