Angular PrimeNG ChartModel Chart Types

Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. It provides a lot of templates, components, theme design, an extensive icon library, and much more. In this article, we are going to learn Angular PrimeNG ChartModel Types.

The ChartModel Component is used to create different types of charts and is based on Chart.js, an open-source HTML5-based charting library. The ChartModel Types has six different types of charts: pie, doughnut, line(line or horizontalBar), bar, radar, and polarArea.

Syntax:

<p-chart #chart type="bar" 
    [data]="..." 
    [responsive]="...">
</p-chart>

Creating Angular application & Module Installation:

Step 1: Create an Angular application using the following command.

ng new geeks_angular

Step 2: After creating your project folder i.e. geeks_angular, move to it using the following command.

cd geeks_angular

Step 3: Install PrimeNG in your given directory.

npm install primeng --save
npm install primeicons --save

Project Structure: The project structure will look like the following:

Steps to run the application: Run the below command to see the output

ng serve --save

Example 1: Below is the example code that illustrates the use of Angular PrimeNG ChartModel Types. In the following example, we have a Pie chart graph.

• app.component.html:

<h3>Angular PrimeNG ChartModel Types</h3>
<p-chart #chart type="pie"

• app.component.ts:

Javascript

import { Component, ViewChild } from "@angular/core";

        private primengConfig: PrimeNGConfig
    ) {}
    ngOnInit() {
        this.basicData = {
