angular-highcharts

This is a directive for an easy usage of Highcharts with Angular.

{
  "angular": "^21.0.0",
  "highcharts": "^11.4.8"
}

Installation

npm

# install angular-highcharts and highcharts
npm i --save angular-highcharts highcharts

yarn

# install angular-highcharts and highcharts
yarn add angular-highcharts highcharts

Usage Example

Standalone (Recommended)

Since version 21, ChartDirective is standalone. You can import it directly into your components.

// chart.component.ts
import { Component } from '@angular/core';
import { Chart, ChartModule } from 'angular-highcharts';

@Component({
  selector: 'app-chart',
  standalone: true,
  imports: [ChartModule], // or just [ChartDirective]
  template: `
    <button (click)="add()">Add Point!</button>
    <div [chart]="chart"></div>
  `
})
export class ChartComponent {
  chart = new Chart({
    chart: { type: 'line' },
    title: { text: 'Linechart' },
    series: [{
      name: 'Line 1',
      data: [1, 2, 3]
    }]
  });

  add() {
    this.chart.addPoint(Math.floor(Math.random() * 10));
  }
}

Zoneless Support

This library fully supports Angular Zoneless mode. In your main.ts, you can bootstrap your application without zone.js:

import { bootstrapApplication } from '@angular/platform-browser';
import { provideZonelessChangeDetection } from '@angular/core';
import { AppComponent } from './app/app.component';

bootstrapApplication(AppComponent, {
  providers: [
    provideZonelessChangeDetection()
  ]
});

Note: Don't forget to use the modules with the .src suffix for better compatibility with modern bundlers.

// main.ts or app.config.ts
import { HIGHCHARTS_MODULES } from 'angular-highcharts';
import more from 'highcharts/highcharts-more.src';
import exporting from 'highcharts/modules/exporting.src';

bootstrapApplication(AppComponent, {
  providers: [
    { provide: HIGHCHARTS_MODULES, useFactory: () => [more, exporting] }
  ]
});

Note: Don't forget to use the modules with the .src suffix for better compatibility with modern bundlers.

Troubleshooting

Compile Issues

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.
