Installation

To install ng-dygraphs use

npm install ng-dygraphs --save

dygraphs is a dependency and should be installed along with the module.

Usage

and then from your Angular AppModule:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
 
import { AppComponent } from './app.component';
 
// Import ng-dygraphs library
import { NgDygraphsModule } from 'ng-dygraphs';
 
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
 
    // Specify NgDygraphsModule library as an import
    NgDygraphsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Once ng-dygraphs library is imported, you can use ng-dygraphs component in your Angular application:

<!-- You can now use your library component in app.component.html -->
<h1>
  {{title}}
</h1>
<!-- data property needs to be  defined in your controller and in native array format http://dygraphs.com/data.html#array
  
  data = [[new Date("2008/05/07"), 75],
          [new Date("2008/05/08"), 70],
          [new Date("2008/05/09"), 80]
         ];
  
  options = {width: 'auto', labels: ['Date','Temperature'], xlabel: 'X label text', ylabel: 'Y label text', title: 'Working title :)', animatedZooms: true, pointSize: 4}
-->
<ng-dygraphs
  [data]="data"
  [options]="options">
</ng-dygraphs>

Additional settings to include this library in your angular2+ project

example of integration with one of most popular angular2 seeds https://github.com/mgechev/angular-seed/

in /tools/config/project.config.ts

    // Add `NPM` third-party libraries to be injected/bundled.
    this.NPM_DEPENDENCIES = [
      ...this.NPM_DEPENDENCIES,
     { src: 'dygraphs/dist/dygraph.min.js', inject: 'libs' },
     //for version "dygraphs": "1.1.1" use this bellow
     //{ src: 'dygraphs/dygraph-combined.js', inject: 'libs' },
      { src: 'dygraphs/dist/dygraph.min.css', inject: true, vendor: true }
    ];
 
    this.mergeObject(this.SYSTEM_BUILDER_CONFIG, {
      packages: {
        'ng-dygraphs' : {
          main:'lib/index.js',
          defaultExtension: 'js'
        }
      }
    });
      // Add packages (e.g. ng2-translate)
    const additionalPackages: ExtendPackages[] = [{
      name: 'ng-dygraphs',
      // Path to the package's bundle
      path: 'node_modules/ng-dygraphs/lib/index.js'
    }];
    this.addPackagesBundles(additionalPackages);
 
   // in older version of seed you may try this code bellow
   // this.mergeObject(this.SYSTEM_CONFIG_DEV, {
   // paths: {
   //   'ng-dygraphs': 'node_modules/ng-dygraphs/lib/index.js'
   // }
   // });
