Radar Chart in Angular Charts

3 Feb 202624 minutes to read

Radar

To render a radar series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

  1. Set the series type: Define the series type as Radar in your chart configuration. This indicates that the data should be represented as a radar chart, which is ideal for plotting data points on a circular grid.

  2. Inject the RadarSeries module: Use the @NgModule.providers method to inject the RadarSeriesService module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering radar series are available in your chart.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule, ChartAllModule } from '@syncfusion/ej2-angular-charts'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { AreaSeriesService, LineSeriesService, ExportService, ColumnSeriesService, StackingColumnSeriesService, StackingAreaSeriesService, RangeColumnSeriesService, ScatterSeriesService, PolarSeriesService, CategoryService, RadarSeriesService, SplineSeriesService} from '@syncfusion/ej2-angular-charts'



import { Component, OnInit } from '@angular/core';
import { chartData } from './datasource';

@Component({
imports: [
         ChartModule, ButtonModule, ChartAllModule
    ],

providers: [ AreaSeriesService, LineSeriesService, ExportService, ColumnSeriesService, StackingColumnSeriesService, StackingAreaSeriesService, RangeColumnSeriesService, ScatterSeriesService, PolarSeriesService, CategoryService, RadarSeriesService, SplineSeriesService],
standalone: true,
    selector: 'app-container',
    template: ` <ejs-chart id='chartcontainer' [title]='title' >
            <e-series-collection>
                <e-series [dataSource]='data' type='Radar' xName='x' yName='y' drawType='Line'> </e-series>
            </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public title?: string;
    public data?: Object[];
    ngOnInit(): void {
        this.data = chartData;
        this.title = 'Efficiency of oil-fired power production';

    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
export let chartData: object[] = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 },
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];

Draw type

Similar to the polar chart, use the drawType property to change the series plotting type in a Radar chart to line, column, area, range column, spline, scatter, stacking area, spline area, or stacking column. The default value of drawType is Line.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule, ChartAllModule } from '@syncfusion/ej2-angular-charts'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { AreaSeriesService, LineSeriesService, ExportService, ColumnSeriesService, StackingColumnSeriesService, StackingAreaSeriesService, RangeColumnSeriesService, ScatterSeriesService, PolarSeriesService, CategoryService, RadarSeriesService, SplineSeriesService} from '@syncfusion/ej2-angular-charts'



import { Component, OnInit } from '@angular/core';
import { chartData } from './datasource';

@Component({
imports: [
         ChartModule, ButtonModule, ChartAllModule
    ],

providers: [ AreaSeriesService, LineSeriesService, ExportService, ColumnSeriesService, StackingColumnSeriesService, StackingAreaSeriesService, RangeColumnSeriesService, ScatterSeriesService, PolarSeriesService, CategoryService, RadarSeriesService, SplineSeriesService],
standalone: true,
    selector: 'app-container',
    template: ` <ejs-chart id='chartcontainer' [title]='title' >
            <e-series-collection>
                <e-series [dataSource]='data' type='Radar' xName='x' yName='y' drawType='Line'> </e-series>
            </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public title?: string;
    public data?: Object[];
    ngOnInit(): void {
        this.data = chartData;
        this.title = 'Efficiency of oil-fired power production';

    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
export let chartData: object[] = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 },
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];

Binding data with series

You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName and yName properties.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule, ChartAllModule } from '@syncfusion/ej2-angular-charts'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { AreaSeriesService, LineSeriesService, ExportService, ColumnSeriesService, StackingColumnSeriesService, StackingAreaSeriesService, RangeColumnSeriesService, ScatterSeriesService, PolarSeriesService, CategoryService, RadarSeriesService, SplineSeriesService} from '@syncfusion/ej2-angular-charts'



import { Component, OnInit } from '@angular/core';
import { chartData } from './datasource';

@Component({
imports: [
         ChartModule, ButtonModule, ChartAllModule
    ],

providers: [ AreaSeriesService, LineSeriesService, ExportService, ColumnSeriesService, StackingColumnSeriesService, StackingAreaSeriesService, RangeColumnSeriesService, ScatterSeriesService, PolarSeriesService, CategoryService, RadarSeriesService, SplineSeriesService],
standalone: true,
    selector: 'app-container',
    template: ` <ejs-chart id='chartcontainer' [title]='title' >
            <e-series-collection>
                <e-series [dataSource]='data' type='Radar' xName='x' yName='y' drawType='Line'> </e-series>
            </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public title?: string;
    public data?: Object[];
    ngOnInit(): void {
        this.data = chartData;
        this.title = 'Efficiency of oil-fired power production';

    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
export let chartData: object[] = [
    { x: 2005, y: 28 }, 
    { x: 2006, y: 25 },
    { x: 2007, y: 26 }, 
    { x: 2008, y: 27 },
    { x: 2009, y: 32 }, 
    { x: 2010, y: 35 }, 
    { x: 2011, y: 30 }
];

Series customization

    public title?: string;
    public primaryYAxis?: Object;
    public data?: Object[];


    ngOnInit(): void {
        this.data = chartData;
        this.primaryXAxis = {
            title: 'Year', startAngle: 90,
            minimum: 2004, maximum: 2012, interval: 1
            };
        this.title = 'Efficiency of oil-fired power production';

    }
}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';

    public primaryXAxis?: Object;
    public title?: string;
    public data?: Object[];
    ngOnInit(): void {
        this.data = radarData;
        this.primaryXAxis = {
            title: 'Year', coefficient: 50,
            minimum: 2004, maximum: 2012, interval: 1

Events

Series render

The seriesRender event enables modification of series properties (for example, data, fill, or name) immediately before rendering. Use this event to adjust series appearance or to dynamically swap data sources..

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule, ChartAllModule } from '@syncfusion/ej2-angular-charts'
import { ISeriesRenderEventArgs } from '@syncfusion/ej2-charts'
import { ButtonModule } from '@syncfusion/ej2-angular-buttons'
import { AreaSeriesService, LineSeriesService, ExportService, ColumnSeriesService, StackingColumnSeriesService, StackingAreaSeriesService, RangeColumnSeriesService, ScatterSeriesService, PolarSeriesService, CategoryService, RadarSeriesService, SplineSeriesService} from '@syncfusion/ej2-angular-charts'



import { Component, OnInit } from '@angular/core';
import { radarData } from './datasource';
@Component({
imports: [
         ChartModule, ButtonModule, ChartAllModule
    ],

providers: [ AreaSeriesService, LineSeriesService, ExportService, ColumnSeriesService, StackingColumnSeriesService, StackingAreaSeriesService, RangeColumnSeriesService, ScatterSeriesService, PolarSeriesService, CategoryService, RadarSeriesService, SplineSeriesService],
standalone: true,
    selector: 'app-container',
    template: ` <ejs-chart id='chartcontainer' (seriesRender)='seriesRender($event)' [primaryXAxis]='primaryXAxis'

})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public title?: string;
    public primaryYAxis?: Object;
    public data?: Object[];
    public emptyPointSettings?: Object;

    ngOnInit(): void {
        this.data = radarData;
        this.primaryXAxis = {
            title: 'Year', startAngle: 90,
            minimum: 2004, maximum: 2012, interval: 1
            };
        this.title = 'Efficiency of oil-fired power production';
    }
    public seriesRender(args: ISeriesRenderEventArgs) {
        args.fill = '#ff6347';

{ x: 2009, y: 32 },
{ x: 2010, y: 35 },
{ x: 2011, y: 30 }
];

Point render

The pointRender event provides a hook to customize each data point (for example, marker shape, border, or fill) before it is drawn. Use this to apply per-point styling rules or conditional formatting.

                <e-series [dataSource]='data' type='Radar' xName='x' yName='y' [marker]='marker' drawType='Line'> </e-series>
            </e-series-collection>

            minimum: 2004, maximum: 2012, interval: 1
            };
        this.marker = {visible: true};
        this.title = 'Efficiency of oil-fired power production';
