Internationalization in Angular Circular Gauge component

23 Sep 20239 minutes to read

Circular Gauge provides internationalization support for below elements.

• Axis Labels
• Tooltip

For more information about number formatter, you can refer 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 in Circular Gauge using format property in labelStyle.

Numeric Format

In the below example, axis labels are globalized to EUR.

app.component.ts

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

@Component({
    selector: 'app-container',
    template:
    `<ejs-circulargauge id="circular-container">
        <e-axes>
            <e-axis [labelStyle]="labelStyle"></e-axis>
        </e-axes>
    </ejs-circulargauge>`
})
export class AppComponent implements OnInit {
    public labelStyle?: Object;
    ngOnInit(): void {
        // Initialize objects.
        this.labelStyle= {
            // Label format set as currency.
            format: 'c'
        };
    }
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { CircularGaugeModule } from '@syncfusion/ej2-angular-circulargauge';
import { loadCldr, L10n, setCulture, setCurrencyCode } from '@syncfusion/ej2-base';
setCulture('de');
setCurrencyCode('EUR');

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, CircularGaugeModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
})
export class AppModule { }

main.ts

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

Circular Gauge can render its elements from right to left, which improves the user experience for certain language users. To do so, set the enableRtl property to true. When this property is enabled, elements such as the tooltip and legend will be rendered from right to left. Meanwhile, the axis can be rendered from right to left by setting the direction property to AntiClockWise. For more information on axis, click here.

The following example illustrates the right to left rendering of the Circular Gauge.

app.component.ts

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

@Component({
    selector: 'app-container',
    template:
    `<ejs-circulargauge id="circular-container" [enableRtl]="true" [tooltip]="tooltip" [legendSettings]='legendSettings'>
        <e-axes>
            <e-axis direction='AntiClockWise' startAngle=210 endAngle=150 minimum=0 maximum=120 radius='80%' [majorTicks]="majorTicks" [minorTicks]="minorTicks" [lineStyle]="lineStyle" [labelStyle]="labelStyle">
                <e-pointers>
                    <e-pointer value=65 radius='60%' color='#757575' pointerWidth=8 [cap]="cap" [needleTail]="needleTail">
                    </e-pointer>
                </e-pointers>
                <e-ranges>
                    <e-range start=0 end=40 color='#30B32D'></e-range>
