Marker Type

Add different types of markers

You can use different marker objects in maps control by using the marker settings.

To update different marker settings in maps, please follow the given steps:

Step 1:

Initialize the maps control with marker settings. Here, a marker has been added with specified latitude and longitude of California by using the dataSource property. You can customize the shape of the marker using the Shape property and change the border color and width of the marker using the border property as mentioned in the following code example. To know more about the marker settings, please refer to the API documentation.

    selector: 'app-container',
    // specifies the template string for the maps component

enableProdMode();

Step 2:

Injecting MarkerService into NgModule

[app.module.ts]

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent }  from './app.component';
import { MapsModule, MarkerService } from '@syncfusion/ej2-angular-maps';

@NgModule({
  imports:      [ BrowserModule,MapsModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ],
  providers: [MarkerService]
})
export class AppModule { }

Step 3:

Customize the above option for n number of markers as mentioned in the following code example.

Tooltip for Marker

Tooltip is used to display more information about marker on mouse over or touch end event. This can be enabled separately for layer or marker by setting the tooltipSettings.visible property to true. The valuePath property in tooltip takes the field name that presents in dataSource and displays that value as tooltip text. The following code example illustrates enabling the tooltip for marker to show city name field. To know more about tooltip, please refer to the API documentation.
