Angular PrimeNG Line Chart Component

Last Updated : 28 Apr, 2025

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 Line Chart Component

A line chart or line graph is a type of chart used to display information as a series of data points that act as a dataset called markers connected with lines. The line chart can be modified to save single axes or multiple axes.

Syntax:

<p-chart type="line" [data]="basicData"></p-chart>

app.component.ts:

this.basicData = {
    labels: ['January', 'February', 'March', 
        'April', 'May', 'June', 'July'],
    datasets: [
        {
            label: '2020',
            data: [65, 59, 80, 81, 56, 55, 40],
        },
    ],
};

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:

Example 1: In the following example, we have a Line chart with two datasets.

import { ToastModule } from 'primeng/toast';
import { RippleModule } from 'primeng/ripple';
import { ImageModule } from 'primeng/image';
import { ChartModule } from 'primeng/chart';

        ImageModule,
        ChartModule,
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
})
export class AppModule { }

Output:

Example 2: In the following example, we have applied some styles to the Line chart.
