Hello to all, welcome to therichpost.com. In this post, I will tell you, Angular 8 chartjs working example.

Chartjs is very popular and very easy to use. On my blog, I have share many posts related to chartjs.

Now, I am using chartjs in angular 8 and in this I will static data but In my future posts, I will dynamic data from laravel 6.

chartjs-in-angular8
chartjs-in-angular8

Here is the working code snippet and please use this carefully:

1. Here are the basics commands, you need to use into your terminal or command prompt to install Angular 8 fresh set up:

$ npm install -g @angular/cli //Setup Angular8 atmosphere

$ ng new angular8chartjs //Install New Angular App

/**You need to update your Nodejs also for this verison**/

$ cd angular8chartjs //Go inside the Angular 8 Project

2. After Install Angular 8 fresh setup and go inside the Angular 8 setup, run below command into your terminal to install chartjs module:

npm install --save chart.js

3. After all above setup, here is code, you need to add into your app.component.ts file:

import { Component } from '@angular/core';
import * as Chart from 'chart.js'
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'angular8chartjs';
  canvas: any;
  ctx: any;
  ngAfterViewInit() {
    this.canvas = document.getElementById('myChart');
    this.ctx = this.canvas.getContext('2d');
    let myChart = new Chart(this.ctx, {
      type: 'pie',
      data: {
          labels: ["New", "In Progress", "On Hold"],
          datasets: [{
              label: '# of Votes',
              data: [1,2,3],
              backgroundColor: [
                  'rgba(255, 99, 132, 1)',
                  'rgba(54, 162, 235, 1)',
                  'rgba(255, 206, 86, 1)'
              ],
              borderWidth: 1
          }]
      },
      options: {
        responsive: false,
        display:true
      }
    });
  }
}

4. Now, add below code into your app.component.html file:

<canvas id="myChart" width="700" height="400"></canvas>

In this end, don’t forget to run ng serve command into your terminal and you will get this url localhost:4200

    Hi,

    I’ve built a angular project sample with chart.js. The type of chart I’m working on is the vertical bar type chart.
    I’m currently able to generate the bar chart with appropriate data. I’m currently working on the tooltip style.
    I need your help in setting the code for tooltips caret pointing downwards.

    I found that using tooltip property ‘yAlign:”bottom”‘ will resolve my need while googling. However, using ‘yAlign’ property in my project throws error stating that ‘yAlign’ not a property in chart.js
    This is for your info that I’m using the chart .js version 2.7.2 and Angular 8+.

    Could you please guide me on this regards?

    Okay sure, I will update you on this.
