Angular Highcharts - Overview
HighChart Angular Wrapper is a open source angular based component to provides an
elegant and feature rich Highcharts visualizations within an Angular application and can be
used along with Angular components seamlessly. There are chapters discussing all the
basic components of Highcharts with suitable examples within a Angular application.
Features
Compatible − All modern browsers are supported along with iPhone/iPad
browsers and Internet Explorer 6 onwards. Modern browsers use SVG for the
graphics rendering and in legacy Internet Explorer graphics are drawn using VML.
Pure TypeScript − No JavaScript is required as complete Highcharts API is
available in TypeScript.
No Flash − No requirement of client side plug-ins like Flash player or Java as
Highcharts is uses native browser technologies and charts can run without
modification on modern mobile devices.
Clean Syntax − Most of the methods are chain-able thus configuration options of
the chart can be managed using syntax as tight as JSON.
Dynamic − Series and points can be added dynamically any time after chart
creation. Event hooks supported. Server interactions are supported.
Documented − Highcharts APIs are thoroughly documented with numerous code
and syntax examples.
Angular Highcharts - Environment Setup
This tutorial will guide you on how to prepare a development environment to start your
work with Highcharts and Angular Framework. In this chapter, we will discuss the
Environment Setup required for Angular 6. To install Angular 6, we require the following −
Nodejs
Npm
Angular CLI
IDE for writing your code
Nodejs has to be greater than 8.11 and npm has to be greater than 5.6.
Nodejs
To check if nodejs is installed on your system, type node -v in the terminal. This will help
you see the version of nodejs currently installed on your system.
C:\>node -v
v8.11.3
If it does not print anything, install nodejs on your system. To install nodejs, go the
homepage https://nodejs.org/en/download/
of nodejs and install the package based on
your OS.
The homepage of nodejs will look like the following −
Based on your OS, install the required package. Once nodejs is installed, npm will also get
installed along with it. To check if npm is installed or not, type npm -v in the terminal. It
should display the version of the npm.
C:\>npm -v
5.6.0
Angular 6 installations are very simple with the help of angular CLI. Visit the homepage
https://cli.angular.io/
of angular to get the reference of the command.
Type npm install -g @angular/cli, to install angular cli on your system.
You will get the above installation in your terminal, once Angular CLI is installed. You can
use any IDE of your choice, i.e., WebStorm, Atom, Visual Studio Code, etc.
Install Highcharts
Run the following command to install highchart module in the project created.
highchartsApp>npm install highcharts --save
+ highcharts@6.2.0
added 1 package in 137.534s
Run the following command to install highchart wrapper module in the project created.
highchartsApp>npm install highcharts-angular --save
+ highcharts-angular@2.3.1
added 1 package in 20.93s
Add the following entry in highchartsApp.module.ts file
import { HighchartsChartComponent } from 'highcharts-angular';
declarations: [
...
HighchartsChartComponent
],
Angular Highcharts - Configuration Syntax
In this chapter, we will showcase the configuration required to draw a chart using the
Highcharts API in Angular.
Step 1 - Create Angular Application
Follow the following steps to update the Angular application we created in Angular 6 Project Setup chapter −
Step
Description
1
Create a project with a name highchartsApp as explained in the Angular 6 - Project
Setup chapter.
2
Modify app.module.ts, app.component.ts and app.component.html as explained below.
Keep rest of the files unchanged.
3
Compile and run the application to verify the result of the implemented logic.
Following is the content of the modified module descriptor app.module.ts.
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { HighchartsChartComponent } from 'highcharts-angular';
@NgModule({
declarations: [
AppComponent,
HighchartsChartComponent
],
imports: [
BrowserModule,
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Following is the content of the modified HTML host file app.component.html.
[Highcharts] = "highcharts"
[options] = "chartOptions"
style = "width: 100%; height: 400px; display: block;"
We'll see the updated app.component.ts in the end after understanding configurations.
Step 2 − Use Configurations
Create Highcharts and create chartOptions
highcharts = Highcharts;
chartOptions = {
}
Create Chart
Configure the type, title and sub-title of the chart using chartOptions.
chart: {
type: "spline"
},
xAxis
Configure the ticker to be displayed on the X-Axis using chartOptions.
xAxis:{
categories:["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"
},
yAxis
Configure the title to be displayed on the Y-Axis using chartOptions.
yAxis: {
title:{
text:"Temperature °C"
}
},
tooltip
Configure the tooltip. Put suffix to be added after value (y-axis) using chartOptions.
tooltip: {
valueSuffix:" °C"
},
series
Configure the data to be displayed on the chart using chartOptions. Series is an array
where each element of this array represents a single line on the chart.
series: [
{
name:
data:
},
{
name:
data:
},
{
name:
data:
},
{
name:
data:
}
]
'Tokyo',
[7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2,26.5, 23.3, 18.3, 13.9, 9.6]
'New York',
[-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8,24.1, 20.1, 14.1, 8.6, 2.5]

Example
Consider the following example to further understand the Configuration Syntax −
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 {
highcharts = Highcharts;
chartOptions = {
chart: {
type: "spline"
},
title: {
text: "Monthly Average Temperature"
},
subtitle: {
text: "Source: WorldClimate.com"
},
xAxis:{
categories:["Jan", "Feb", "Mar", "Apr", "May", "Jun",
"Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]
},
yAxis: {
title:{
text:"Temperature °C"
}
},
tooltip: {
valueSuffix:" °C"
},
series: [
{
name:
data:
},
{
name:
data:
},
{
name:
data:
},
{
name:
data:
}
]
};
}
Result
