Internationalization in Angular Treemap component

7 Nov 202322 minutes to read

The TreeMap 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.

Numeric format

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

app.component.ts
app.module.ts
main.ts
import { Component } from '@angular/core';
import { setCulture, setCurrencyCode } from '@syncfusion/ej2-base';
setCulture('de');
setCurrencyCode('EUR');

@Component({
    selector: 'app-container',
    template: `<ejs-treemap id='container' style='display: block;' [dataSource]='data' weightValuePath='GDP' format='c' useGroupingSeparator= 'true' [tooltipSettings]='tooltip'
   >
    </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 tooltip: object = {
        visible: true,
    };
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { TreeMapModule, TreeMapTooltipService, TreeMapAllModule } from '@syncfusion/ej2-angular-treemap';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, TreeMapModule, TreeMapAllModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
	providers: [TreeMapTooltipService]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

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 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.

app.component.ts
app.module.ts
main.ts
import { Component } from '@angular/core';

@Component({
    selector: 'app-container',
    template: `<ejs-treemap id='container' style='display: block;'  [dataSource]='data' weightValuePath='count' [legendSettings]='legendSettings' colorValuePath= 'color' enableRtl='true'
    [leafItemSettings]='leafItemSettings' >
    </ejs-treemap>`
})
export class AppComponent {
    public data: object[] = [{ Car:'Mustang', Brand:'Ford', count:232, color: '#71B081' },
                       { Car:'EcoSport', Brand:'Ford', count:121,  color: '#5A9A77' },
                       { Car:'Swift', Brand:'Maruti', count:143, color: '#498770' },
                       { Car:'Baleno', Brand:'Maruti', count:454, color: '#39776C' },
                       { Car:'Vitara Brezza', Brand:'Maruti', count:545 , color: '#266665' },
                       { Car:'A3 Cabriolet', Brand:'Audi',count:123, color: '#124F5E' }

    ];
    public legendSettings: object= {
        visible: true,
        position:'Top'

    };
    public leafItemSettings:object= {
        labelPath: 'Car'
     };
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { TreeMapModule, TreeMapLegendService, TreeMapTooltipService, TreeMapAllModule } from '@syncfusion/ej2-angular-treemap';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, TreeMapModule, TreeMapAllModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
	providers: [TreeMapLegendService, TreeMapTooltipService]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

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

app.component.ts
app.module.ts
main.ts
import { Component } from '@angular/core';

@Component({
    selector: 'app-container',
    template: `<ejs-treemap id='container' style='display: block;' [palette] ='palette' [dataSource]='data' weightValuePath='count' [tooltipSettings]='tooltipSettings' colorValuePath = 'color' enableRtl ='true'
    [leafItemSettings]='leafItemSettings' >
    </ejs-treemap>`
})
export class AppComponent {
    public data: object[] = [{ fruit:'Apple', count:5000 },
                       { fruit:'Mango', count:3000 },
                       { fruit:'Orange', count:2300 },
                       { fruit:'Banana', count:500 },
                       { fruit:'Grape', count:4300 },
                       { fruit:'Papaya', count:1200 },
                       { fruit:'Melon', count:4500 }

    ];
    public tooltipSettings: object= {
        visible: true,
        format:'${count} : ${fruit}'
    };
    public leafItemSettings:object= {
        labelPath: 'fruit'
     };
    public palette:object =['#71B081','#5A9A77', '#498770', '#39776C', '#266665','#124F5E'];
}

import { AppComponent } from './app.component';
import { TreeMapModule, TreeMapLegendService, TreeMapTooltipService, TreeMapAllModule } from '@syncfusion/ej2-angular-treemap';

Treemap Item Rendering Direction

The direction of TreeMap item is TopLeftBottomRight by default and customize the rendering direction of the TreeMap item by setting the renderDirection property.

The TreeMap can be rendered in the following directions:

TopLeftBottomRight
TopRightBottomLeft
BottomRightTopLeft
BottomLeftTopRight

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

app.component.ts
app.module.ts
main.ts
import { Component } from '@angular/core';

@Component({
    selector: 'app-container',
    template: `<ejs-treemap id='container' style='display: block;' [palette] ='palette' [dataSource]='data' weightValuePath='count'
    renderDirection='TopLeftBottomRight' >
    </ejs-treemap>`
})
export class AppComponent {
    public data: object[] = [{ fruit:'Apple', count:5000 },
                       { fruit:'Mango', count:3000 },
                       { fruit:'Orange', count:2300 },
                       { fruit:'Banana', count:500 },
                       { fruit:'Grape', count:4300 },
                       { fruit:'Papaya', count:1200 },
                       { fruit:'Melon', count:4500 }
    ];
    public leafItemSettings:object= {
        labelPath: 'fruit'
     };
    public palette:object =['#71B081','#5A9A77', '#498770', '#39776C', '#266665','#124F5E'];
