18 Nov 202217 minutes to read

To render a funnel series, use the series type as Funnel and inject, the FunnelSeries module into the @NgModule.providers.

To known about funnel charts, you can check on this video:

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { funnelData } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container">
        <e-accumulation-series-collection>
            <e-accumulation-series width='330px' type='Funnel' [dataSource]='funneldata' xName='x' yName='y'></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public funneldata: Object[];
    ngOnInit(): void {
        this.funneldata = funnelData;
    }

}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Size

The size of the funnel chart can be customized by using the width and height properties.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { funnelData } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container">
        <e-accumulation-series-collection>
            <e-accumulation-series  width='60%'  height='80%' type='Funnel' [dataSource]='funneldata' xName='x' yName='y' [dataLabel]='datalabel'></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public funneldata: Object[];
    ngOnInit(): void {
        this.datalabel = { visible: true, name: 'text', position: 'Inside' };
        this.funneldata = funnelData;
    }

}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Neck Size

The funnel’s neck size can be customized by using the neckWidth and neckHeight properties.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { funnelData } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container">
        <e-accumulation-series-collection>
            <e-accumulation-series type='Funnel' [dataSource]='funneldata' xName='x' yName='y' [dataLabel]='datalabel' [neckWidth]='neckWidth'
             [neckHeight]='neckHeight'></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public funneldata: Object[];
    public neckWidth: string = '25%';
    public neckHeight:'5%'
    ngOnInit(): void {
        this.funneldata = funnelData;
    }

}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Gap between the segments

Funnel chart provides options to customize the space between the segments by using the gapRatio property of the series. It ranges from 0 to 1.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { funnelData } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container">
        <e-accumulation-series-collection>
            <e-accumulation-series  type='Funnel' [dataSource]='funneldata' xName='x' yName='y' [dataLabel]='datalabel' [gapRatio]="gapRatio"></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public funneldata: Object[];
    public gapRatio: number = 0.08;
    ngOnInit(): void {
        this.funneldata = funnelData;
    }

}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Explode

Points can be exploded on mouse click by setting the explode property to true. You can also explode the point on load using explodeIndex. Explode distance can be set by using explodeOffset property.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { funnelData } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container">
        <e-accumulation-series-collection>
            <e-accumulation-series  type='Funnel'[dataSource]='funnelData' xName='x' yName='y' [explode]='explode' [explodeAll]='explodeAll'
            [explodeIndex]='explodeIndex'></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public funnelData: Object[];
    public explode: boolean;
    public explodeIndex: number;
    public explodeAll: boolean;
    ngOnInit(): void {
        this.explode = true;
        this.explodeIndex = 3;
        this.explodeOffset = '30px';
        this.explodeAll = false;
        this.funnelData = funnelData;
    }

}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Smart Data Label

It provides the data label smart arrangement of the funnel and pyramid series. The overlap data label will be placed on left side of the funnel/pyramid series.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { funnelDataSource } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container" [legendSettings]="legendSettings" [tooltip]="tooltip" title="Top population countries in the world 2017">
        <e-accumulation-series-collection>
            <e-accumulation-series  type='Funnel' [dataSource]='funnelData' xName='x' yName='y' neckWidth='15%'
            neckHeight='18%' [dataLabel]='dataLabel' name="2017 Population" explode="false"></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public funnelData: Object[];
    public dataLabel: Object;
    public legendSettings: Object;
    public tooltip: Object;
    ngOnInit(): void {
        this.funnelData = funnelDataSource;
        this.dataLabel = {
            visible: true, position: 'Outside',
            connectorStyle: { length: '6%' }, name: 'text',
        };
        this.legendSettings = {visible = false};
        this.tooltip = {
            enable: true, format: '${point.x} : <b>${point.y}</b>'
        };
    }
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**

@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [FunnelSeriesService, AccumulationTooltipService, CategoryService, AccumulationDataLabelService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Customization

Individual points can be customized using the pointRender event.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { funnelData } from 'datasource.ts';
import { IAccTextRenderEventArgs, IAccPointRenderEventArgs } from '@syncfusion/ej2-charts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container" (pointRender)="onPointRender($event)">
        <e-accumulation-series-collection>
            <e-accumulation-series  type='Funnel' [dataSource]='funneldata' xName='x' yName='y' [dataLabel]='datalabel' [gapRatio]="gapRatio"
             ></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public funneldata: Object[];
    public gapRatio: number = 0.08;
    public onPointRender: Function;
    ngOnInit(): void {
        this.onPointRender = (args: IAccPointRenderEventArgs): void {
            if ((args.point.x as string).indexOf('Downloaded') > -1) {
                args.fill = '#D3D3D3';
            }
            else {
            args.fill = '#597cf9';
        }
        }
        this.funneldata = funnelData;
    }
