Setting the size for Maps

The width and height of the Maps can be set using the width and height properties in the Maps component. Percentage or pixel values can be used for the height and width values.

app.component.ts
app.module.ts
main.ts
import { Component, ViewEncapsulation } from '@angular/core';
import { world_map } from './world-map';

@Component({
  selector: 'app-container',
  // specifies the template string for the maps component
  template:
    `<ejs-maps id='rn-container' height='200px' width='200px'>
     <e-layers>
         <e-layer [shapeData]='shapeData' [shapeSettings]="shapeSettings"></e-layer>
    </e-layers>
    </ejs-maps>`,
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {
    public shapeData = world_map;
    public shapeSettings = {
        autofill: true
    }
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { MapsModule } from '@syncfusion/ej2-angular-maps';

        BrowserModule, MapsModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
   
})
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);

Customizing Maps area

By default, the background color of the shape maps is set as white. To modify the background color of the Maps area, the background property in the mapsArea is used. The border of the Maps area can be customized using border property in the mapsArea.

app.component.ts
app.module.ts
main.ts
import { Component, ViewEncapsulation } from '@angular/core';
import { world_map } from './world-map';

@Component({
  selector: 'app-container',

 */
@NgModule({
    imports: [
        BrowserModule, MapsModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
   
})
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);

Customizing the shapes

The following properties are available in shapeSettings to customize the shapes of the Maps.

fill - To apply the fill color to the all the shapes.
autofill - To apply the palette colors to the shapes if it is set as true.
palette - To set the custom palette for the shapes.
border - To customize the color, width and opacity of the border of the shapes.

main.ts
import { Component, ViewEncapsulation } from '@angular/core';
import { world_map } from './world-map';

@Component({
  selector: 'app-container',
  // specifies the template string for the maps component
  template:
    `<ejs-maps id='rn-container'>
    <e-layers>
    <e-layer [shapeData]='shapeData' [shapeSettings]="shapeSettings"></e-layer>
    </e-layers>
  </ejs-maps>`,
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {
  public shapeData = world_map;
  public shapeSettings = {
      autofill: true,
      palette: ['#C7DE6C', '#59A076', '#88D0BC', '#FEA78C', '#FFC557'],
      border: {
          color: '#FEE1DD',
          width: 3
      },
      dashArray: '1',
      opacity: 0.9
  };
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { MapsModule } from '@syncfusion/ej2-angular-maps';
/**

})
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);

Setting color to the shapes from the data source

The color for each shape in the Maps can be set using the colorValuePath property of shapeSettings. The value for the colorValuePath property is the field name from the data source of the shapeSettings which contains the color values.

app.component.ts
app.module.ts
main.ts
import { Component, ViewEncapsulation } from '@angular/core';
import { world_map } from './world-map';

@Component({
  selector: 'app-container',
  // specifies the template string for the maps component
  template:
    `<ejs-maps id='rn-container'>
    <e-layers>
    <e-layer [shapeData]='shapeData' [shapePropertyPath]='shapePropertyPath' [shapeDataPath]='shapeDataPath'  [dataSource]='dataSource' [shapeSettings]="shapeSettings"></e-layer>
    </e-layers>
  </ejs-maps>`,
  encapsulation: ViewEncapsulation.None
})
export class AppComponent {
    public shapeData = world_map;
    public shapePropertyPath = 'continent';
    public shapeDataPath = 'continent';
    public dataSource = [
        { continent: "North America", color: '#71B081' },
        { continent: "South America", color: '#5A9A77' },
        { continent: "Africa", color: '#498770' },
        { continent: "Europe", color: '#39776C' },
        { continent: "Asia", color: '#266665' },
        { continent: "Oceania", color: '#124F5E' }
    ]
    public shapeSettings = {
        colorValuePath: 'color'
  };
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { MapsModule } from '@syncfusion/ej2-angular-maps';
/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, MapsModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent]
   
})
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);

Applying border to individual shapes

The border of each shape in the Maps can be customized using the borderColorValuePath and borderWidthValuePath properties to modify the color and the width of the border respectively. The field name in the data source of the layer which contains the color and the width values must be set in the borderColorValuePath and borderWidthValuePath properties respectively. If the values of borderWidthValuePath and borderColorValuePath do not match with the field name from the data source, then the color and width of the border will be applied to the shapes using the border property in the shapeSettings.

        { continent: "Africa", color: '#498770', borderColor: '#FFCC99', width: 2 },
        { continent: "Europe", color: '#39776C', borderColor: '#66B2FF', width: 2 },
        { continent: "Asia", color: '#266665', borderColor: '#999900', width: 2 },
        { continent: "Oceania", color: '#124F5E', borderColor: 'blue', width: 2 }
    ]
    public shapeSettings = {
        borderColorValuePath: 'borderColor',
        borderWidthValuePath: 'width',
        colorValuePath: 'color'
  };

Projection type

The Maps component supports the following projection types:

Mercator
Equirectangular
Miller
Eckert3
Eckert5
Eckert6
Winkel3
AitOff

By default, the Maps are rendered by the Mercator projection type in which the Maps are rendered based on the coordinates. So, the Maps is not stretched. To change the type of projection in the Maps, the projectionType property is used.
