Angular PrimeNG Polar Area 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 Polar Area Chart Component in Angular PrimeNG.
Polar area charts are similar to pie charts, but each segment has the same angle – the radius of the segment differs depending on the value.
Angular PrimeNG Polar Area Chart Attributes:
- data: It represents the data that is to be displayed.
- options: It represents the options to be customized in the chart.
Syntax
<p-chart type="polarArea" [data]="data" [options]="chartOptions" > </p-chart>

Project Structure: It will look like the following:
Example 1: This example describes the Polar Area Chart Component in Angular PrimeNG, by implementing only 1 Dataset.
