Polar Chart in Angular Charts

Polar

To render a polar 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 Polar in your chart configuration. This indicates that the data should be represented as a polar chart, which is ideal for plotting data points on a circular graph.

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

app.component.ts

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 { 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' [primaryXAxis]='primaryXAxis'
            [title]='title' >
            <e-series-collection>
                <e-series [dataSource]='data' type='Polar' xName='x' yName='y' drawType='Line'> </e-series>
            </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public title?: string;
    public primaryYAxis?: Object;
    public data?: 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';

    }
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

datasource.ts

export let radarData: 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.

app.component.ts

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 { 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' [primaryXAxis]='primaryXAxis'
            [title]='title' >
            <e-series-collection>
                <e-series [dataSource]='data' type='Polar' xName='x' yName='y' drawType='Line'> </e-series>
            </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public title?: string;
    public primaryYAxis?: Object;
    public data?: 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';

    }
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

datasource.ts

export let radarData: 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 Types

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

Line

To render a line draw type, you need to follow a few steps to configure it correctly.

1. Set the Series Type: Define the series drawType as Line in your chart configuration. This indicates that the data should be represented as a polar line chart, with lines connecting each data point.

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

The isClosed property specifies whether to join the start and end points of a line series used in a polar chart to form a closed path. The default value of isClosed is true.

Spline

To render a spline draw type, you need to follow a few steps to configure it correctly.

1. Set the Series Type: Define the series drawType as Spline in your chart configuration. This indicates that the data should be represented as a polar spline chart, with smooth, curved lines connecting each data point.

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

Range Column

To render a range column draw type, you need to follow a few steps to configure it correctly.

1. Set the Series Type: Define the series drawType as RangeColumn in your chart configuration. This indicates that the data should be represented as a polar range column chart, where each column spans a range of values.

2. Inject the RangeColumnSeries Module: Use the @NgModule.providers method to inject the RangeColumnSeriesService module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering polar range column series are available in your chart.

To render an spline area draw type, you need to follow a few steps to configure it correctly.

1. Set the Series Type: Define the series drawType as SplineArea in your chart configuration. This indicates that the data should be represented as a polar spline area chart, where the series is drawn with smooth, curved lines connecting each data point, and the area beneath the line is filled with color.

2. Inject the SplineAreaSeries Module: Use the @NgModule.providers method to inject the SplineAreaSeriesService module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering polar spline area series are available in your chart.

Empty points

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

Mode

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