How To Create Google Donut Chart In Angular

In this post, you will discover how to add a Donut chart to Google Charts.

The pieHole option should be set to a number between 0 and 1, corresponding to the ratio of radii between the hole and the chart. Numbers between 0.4 and 0.6 will look best on most charts. Values equal to or greater than 1 will be ignored, and a value of 0 will completely shut your piehole.

Step 1:

Create a New Application

ng new DonuteChart

Step 2:

Install Following Package

npm install angular-google-charts

Step 3:

Include the GoogleChartsModule in your app. The module.ts file

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { GoogleChartsModule } from 'angular-google-charts';
  declarations: [
  imports: [
  providers: [],
  bootstrap: [AppComponent]
export class AppModule { }

Step 4:

Insert the following code into your app.component.ts file.

import { Component, OnInit } from '@angular/core';

declare let google: any;

  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
export class AppComponent implements OnInit {
  name = 'Angular';

    ngOnInit() {
  drawChart() {
    google.charts.load('current', {'packages':['corechart']});

      function drawVisualization() {
        var data = google.visualization.arrayToDataTable([
          ['Task', 'Hours per Day'],
          ['Work',     11],
          ['Eat',      2],
          ['Commute',  2],
          ['Watch TV', 2],
          ['Sleep',    7]

        var options = {
          title: 'My Daily Activities',
          pieHole: 0.4,

        var chart = new google.visualization.PieChart(document.getElementById('donutchart'));
        chart.draw(data, options);

Step 5 :

Insert the following code into your app.component.html file

<div #chartDiv id="donutchart"></div>

Step 6:

Run your application

ng serve
