Angular PrimeNG Combo Chart Component

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. In this article, we will see the Angular PrimeNG Combo Chart Component.

The Combo Chart Component provides various kinds of charts that can be combined in the same graph, in order to visualize the different datasets at a moment.

Syntax:

<p-chart type="bar" 
         [data]="data" 
         [options]="chartOptions">
</p-chart>

Creating Angular application & Module Installation:

ng new appname

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

cd appname

Step 3: Install PrimeNG in your given directory:

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