Add Highcharts using Angular 9/8

In this example, we are going to learn about highcharts. We will use Angular 8 or Angular 9 to do this. In our Angular application, a spline chart will be created with highcharts. In order to create the chart, we will use highcharts angular 9/8 and install the highcharts and npm package of highcharts angular. In order to add highcharts, we will use the step by step process, which is described as follows:

Step 1:

In this step, we are going Create New App. The following command will be used to create an Angular app like this:

Step 2:

In this step, we are going to Install Npm Package. We will install the highcharts and npm package of highcharts in Angular.

npm install highcharts --save
npm install highcharts-angular --save

Step 3:

In this step, we are going to Import HighchartsChartComponent. We will use highcharts-angular to import this. After that, we will add the part of declarations. Then we will use a file named app.module.ts and update it like this:

src/app/app.module.ts

import { ModuleOfBrowser  } from '@angular/platform-browser';
import { ModuleOfNg } from '@angular/core';
import { HighchartsChartComponent } from 'highcharts-angular';
   
import { AppComponent } from './app.component';
   
@ModuleOfNg({
  declarations: [
    AppComponent,
    ComponentOfHighchartsChart
  ],
  imports: [
    ModuleOfBrowser 
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Step 4:

In this step, we are going to Use Highcharts. Here, we will use a file named app.component.ts, and we will update it. This file is used to create a data Json array and then forward it to the highcharts option variable. We will use the API to use the service so that we can get the dynamic data.

src/app/app.component.ts

import { Component } from '@angular/core';
import * as Highcharts from 'highcharts';
   
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
    title = 'myHighchart';
   
    data = [{
            name: 'Javatpoint.com',
            data: [500, 700, 555, 444, 777, 877, 944, 567, 666, 789, 456, 654]
         },{
            name: 'Tutorialandexample.com',
            data: [677, 455, 677, 877, 455, 778, 888, 567, 785, 488, 567, 654]
         }];
   
    highcharts = Highcharts;
    chartOptions = {   
      chart: {
         type: "spline"
      },
      title: {
         text: "Monthly Site Visitor"
      },
      xAxis:{
         categories:["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]
      },
      yAxis: {          
         title:{
            text:"Visitors"
         } 
      },
      series: this.data
    };
}

Step 5:

In this step, we are going to Display Highcharts. In this, we will use the HTML file, and then we will update that file like this:

src/app/app.component.html

<h1> Add Highcharts using Angular 8 </h1>
   
<highcharts-chart
   [Highcharts] = "highcharts" 
   [options] = "chartOptions" 
   style = "width: 100%; height: 400px; display: block;">
</highcharts-chart>

Now our above code is ready to run. In order to run the above code, we will use the following command:

When we run this command, the following output will be generated:
