Usage

Import CountriesMapModule in your app.module.ts:

import { CountriesMapModule } from 'countries-map';

@NgModule({
  ...
  imports: [
    ...
    CountriesMapModule,
  ],
})
export class AppModule { }

In your templates, use the <countries-map> component like this:

<countries-map [data]="mapData"></countries-map>

and in the corresponding .ts file:

import { CountriesData } from 'countries-map';
...
public mapData: CountriesData = {
  'ES': { 'value': 416 },
  'GB': { 'value': 94 },
  'FR': { 'value': 255 }
};

Typing

Typing the data input with CountriesData is not mandatory but it is highly recommendable because it will help you correctly define the object to pass to <countries-map>'s [data] attribute.

Attributes

Element <countries-map> accepts the following attributes/inputs:

Interface CountriesData

This interface is a convenience for describing the object to be passed to data attribute.

The list should look like this:

mapData: CountriesData = {
  'ES': { 'value': 416 },
  'GB': { 'value': 94, 'extra': { 'foo': 'bar' } },
  'FR': { 'value': 255, 'extra': { 'baz': 41 } }
};

Actual implementation:

interface CountriesData {
  [countryCode: string]: CountryData;
}
interface CountryData {
  value: number;
  extra?: CountryExtraData;
}
interface CountryExtraData {
  [key: string]: number |string;
}

Events

Element <countries-map> accepts callbacks for the following events:

chartReady

The chartReady event is fired when a chart is completely loaded.

Bind the chartReady event in the countries-map component like this:

<countries-map [data]="mapData" (chartReady)="ready()"></countries-map>

Your ready() function receives no parameters. You can use it like:

public ready() {
  // your logic
}

chartError

The chartError event is fired if there are some errors with a chart.

Bind the chartError event in the countries-map component, like this:

<countries-map [data]="mapData" (chartError)="error($event)"></countries-map>

Your error() function is passed an event which interface looks like this:

interface ChartErrorEvent {
  id: string | CharErrorCode;
  message: string;
  detailedMessage: string;
  options: Object;
}

You can import the ChartErrorEvent interface and CharErrorCode enum in your .ts file:

import { ChartErrorEvent, CharErrorCode } from 'countries-map';

and then use it like:

public error(event: ChartErrorEvent) {
  if (event.id === CharErrorCode.loading) {
    // error was produced during loading
  }
  // your logic
}

See more details about returned values for error event.

chartSelect

The chartSelect event is fired when a chart is selected/clicked.

Bind the chartSelect event in the countries-map component, like this:

<countries-map [data]="mapData" (chartSelect)="select($event)"></countries-map>

Your select() function is passed an event whose interface looks like this:

interface ChartSelectEvent {
  selected: boolean;
  value: number | null;
  country: string;
}

You can import the ChartSelectEvent interface in your .ts file:

import { ChartSelectEvent } from 'countries-map';

and then use it like:

public select(event: ChartSelectEvent) {
  // your logic
}

Styles

You can apply styles to most of the countries-map caption area (if you decide to show it) and map container so that you can integrate your countries-map in your site's look&feel.

These are the classes you can apply styles to, hierarchically displayed, and associated to their wrappers:

• cm-map-content: world map
• cm-caption-container: full caption area
  • cm-simple-caption: main caption section (countryLabel/valueLabel area)
    • cm-country-label: countryLabel keyword or country name (whichever is shown)
      • cm-defaut-label: countryLabel keyword
      • cm-country-name: country name
    • cm-value-label: valueLabel keyword or value label, plus actual value
      • cm-value-text: valueLabel keyword or value label (whichever is shown)
      • cm-value-content: actual value for the current country
  • cm-extended-caption: area for the extra items
    • cm-extended-item: each of the single extra items (made of key and value)
      • cm-extended-label: key of the single extra item
      • cm-extended-value: value of the single extra item
