Radar in Angular Chart component
19 Sep 202424 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:
-
Set the series type: Define the series
type
asRadar
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. -
Inject the RadarSeries module: Use the
@NgModule.providers
method to inject theRadarSeriesService
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'

})
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
Start Angle
You can customize the start angle of the radar series using startAngle
property. By default, startAngle
is 0 degree.
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'

})
export class AppComponent implements OnInit {

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';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

{ x: 2009, y: 32 },
{ x: 2010, y: 35 },
{ x: 2011, y: 30 }
];
Radius
You can customize the radius of the radar series using coefficient
property. By default, coefficient
is 100.

Empty points
Data points with null
or undefined
values are considered empty. Empty data points are ignored and not plotted on the chart.

property to define how empty or missing data points are handled in the series. The default mode for empty points is Gap
.
