Using Highcharts modules

To use Highcharts modules you have to import them and provide them in a factory (required for aot). You can find the list of available modules in the highcharts folder ls -la node_modules/highcharts/modules.

Hint: Highcharts-more is a exception, you find this module in the root folder. Don't forget to use the modules with the .src suffix, minimized highcharts modules are not importable.

Example

// app.module.ts
import { ChartModule, HIGHCHARTS_MODULES } from 'ng-highcharts';
import * as more from 'highcharts/highcharts-more.src';
import * as exporting from 'highcharts/modules/exporting.src';

@NgModule({
  providers: [
    { provide: HIGHCHARTS_MODULES, useFactory: () => [ more, exporting ] } // add as factory to your providers
  ]
})
export class AppModule { }

Troubleshooting

If you expiring typing errors while you build/serve your angular app the following could be helpful:

// override options type with <any>
chart = new Chart({ options } as any);

This is very useful when using gauge chart type.
