A radar chart, also known as a spider chart or web chart, is a graphical representation that displays data on a two-dimensional plane with multiple axes originating from a common center point. This type of chart is often used to visualize and compare the performance or characteristics of different categories across various quantitative variables. Each axis represents a specific data attribute, and the data points are plotted along these axes to form a shape resembling a spider’s web or a star.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { ChartsModule } from 'ng2-charts';
@NgModule({
imports: [ BrowserModule, FormsModule, ChartsModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }

<div style="display: block;">
<canvas baseChart
[datasets]="radarChartData"
