Hello friends, welcome back to my blog. Today in this blog post, I am going to tell you, Angular 11 Customize Pie charts Multiple Demos.
Angular 11 came and if you are new then you must check below two links:
Friends now I proceed onwards and here is the working code snippet for Angular 11 Customize Pie charts Multiple Demos and please use carefully this to avoid the mistakes:
1. Firstly friends we need fresh angular 11 setup and for this we need to run below commands but if you already have angular 11 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:
npm install -g @angular/cli ng new angularchart //Create new Angular Project cd angularchart // Go inside the Angular Project Folder ng serve --open // Run and Open the Angular Project http://localhost:4200/ // Working Angular Project Url
2. Now friends, here we need to run below commands into our project terminal to install bootstrap and jquery modules into our angular application:
npm install --save bootstrap npm i jquery --save npm install chart.js --save ng serve --o
3. Now friends, here we need to add below into our angular.json file:
...
"styles": [
...
"node_modules/bootstrap/dist/css/bootstrap.min.css"
],
"scripts": [
"node_modules/jquery/dist/jquery.min.js",
"node_modules/bootstrap/dist/js/bootstrap.min.js"
]
...
Now run ng serve Command again
4. Now friends we just need to add below code into src/app/app.component.html file to get final out on the web browser:

5. In the end friends, we need to add below code into our src/index.html file:
...
<head>
...
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">
<style>
body {
background-color: #f6f9fb;
}
.text-small {
font-size: 0.9rem;
}
.rounded {
border-radius: 1rem;
}
.position-center {
top: 50%;
left: 50%;
transform: translateX(-50%) translateY(-50%);
}
a {
color: inherit;
text-decoration: none;
}
</style>
...
</head>
6. Now friends we just need to add below code into src/app/app.component.ts file to add pie chart functionality:
...
import * as Chart from 'chart.js';
...
export class AppComponent {
...
//Chartjs
Chart.defaults.RoundedDoughnut = Chart.helpers.clone(Chart.defaults.doughnut);
Chart.controllers.RoundedDoughnut = Chart.controllers.doughnut.extend({
draw: function(ease) {
var ctx = this.chart.ctx;
var easingDecimal = ease || 1;
var arcs = this.getMeta().data;
Chart.helpers.each(arcs, function(arc, i) {
arc.transition(easingDecimal).draw();
var pArc = arcs[i === 0 ? arcs.length - 1 : i - 1];
var pColor = pArc._view.backgroundColor;
var vm = arc._view;
var radius = (vm.outerRadius + vm.innerRadius) / 2;
var thickness = (vm.outerRadius - vm.innerRadius) / 2;
var startAngle = Math.PI - vm.startAngle - Math.PI / 2;
var angle = Math.PI - vm.endAngle - Math.PI / 2;
ctx.save();
ctx.translate(vm.x, vm.y);
ctx.fillStyle = i === 0 ? vm.backgroundColor : pColor;
ctx.beginPath();
ctx.arc(radius * Math.sin(startAngle), radius * Math.cos(startAngle), thickness, 0, 2 * Math.PI);
ctx.fill();
ctx.fillStyle = vm.backgroundColor;
ctx.beginPath();
ctx.arc(radius * Math.sin(angle), radius * Math.cos(angle), thickness, 0, 2 * Math.PI);
ctx.fill();
ctx.restore();
});
}
});
