import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { LinerGaugeModule } from '@syncfusion/ej2-angular-lineargauge;
import { AppComponent } from './app.component';
@NgModule({

})
export class AppModule { }
- Refer to the css file for Angular Linear Gauge in style.css.
Import “../node_modules/@syncfusion/ej2/material.css”
- Add the Angular Linear Gauge component in app.component.html.
<ejs-lineargauge></ejs-lineargauge>
- Now add the axes, major ticks, minor ticks, and pointer in app.component.ts.
public Axes: Object[] = [{
pointers: [{
value: 10,
height: 15,
width: 15,
placement: 'Near',
offset: -50,
markerType: 'Triangle'
}],
majorTicks: {

interval: 10
},
minorTicks: {
color: '#9E9E9E',
interval: 2
},
labelStyle: {

}
}];
- After adding the properties, define the Linear Gauge properties in app.component.html.
<ejs-lineargauge id='defaultContainer' style='display:block;' style='display:block;' orientation='Horizontal' [annotations]='Annotation' [axes]='Axes'> </ejs-lineargauge>
