Funnel in EJ2 JavaScript Accumulation chart control

3 Apr 202524 minutes to read

To render a funnel series, use the series type as Funnel and inject, the FunnelSeries module using the AccumulationChart.Inject(FunnelSeries) method.

var chart = new ej.charts.AccumulationChart({
    width: '500px',
    series: [{
        type: 'Funnel',
        dataSource: [{ x: 'Renewed', y: 18.20, text: 'Renewed 18.20%' },
        { x: 'Subscribe', y: 27.3, text: 'Subscribe 27.3%' },
        { x: 'Support', y: 55.9, text: 'Support 55.9%' },
        { x: 'Downloaded', y: 76.8, text: 'Downloaded 76.8%' },
        { x: 'Visited', y: 100, text: 'Visited 100%' }],
        xName: 'x', yName: 'y',
        dataLabel: { name: 'text', visible: true, position: 'Inside' },
        width: '60%', height: '90%'}
        ],
    title: 'Website visitor',

Size

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

var chart = new ej.charts.AccumulationChart({
    series: [{
        type: 'Funnel',
        dataSource: [{ x: 'Renewed', y: 18.20, text: 'Renewed 18.20%' },
        { x: 'Subscribe', y: 27.3, text: 'Subscribe 27.3%' },
        { x: 'Support', y: 55.9, text: 'Support 55.9%' },
        { x: 'Downloaded', y: 76.8, text: 'Downloaded 76.8%' },
        { x: 'Visited', y: 100, text: 'Visited 100%' }],
        xName: 'x', yName: 'y',
        //Width of the funnel will be 100% of the chart area
        width: '60%',
        //Height of the funnel will be 100% of the chart area
        height: '80%',
        dataLabel: { name: 'text', visible: true, position: 'Inside' },
        }],
    title: 'Website visitor',
}, '#element');

Neck size

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

var chart = new ej.charts.AccumulationChart({
    series: [{
        type: 'Funnel',
        dataSource: [{ x: 'Renewed', y: 18.20, text: 'Renewed 18.20%' },
        { x: 'Subscribe', y: 27.3, text: 'Subscribe 27.3%' },
        { x: 'Support', y: 55.9, text: 'Support 55.9%' },
        { x: 'Downloaded', y: 76.8, text: 'Downloaded 76.8%' },
        { x: 'Visited', y: 100, text: 'Visited 100%' }],
        xName: 'x', yName: 'y',
        //Width of the neck will be set as 25% of the chart area
        neckWidth: '25%', neckHeight:'5%',
        dataLabel: { name: 'text', visible: true, position: 'Inside' },
        }],
    title: 'Website visitor',

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.

var pyramidchart = new ej.charts.AccumulationChart({
    series: [{
        type: 'Funnel',
        dataSource: [{ x: 'Renewed', y: 18.20, text: 'Renewed 18.20%' },
        { x: 'Subscribe', y: 27.3, text: 'Subscribe 27.3%' },
        { x: 'Support', y: 55.9, text: 'Support 55.9%' },
        { x: 'Downloaded', y: 76.8, text: 'Downloaded 76.8%' },
        { x: 'Visited', y: 100, text: 'Visited 100%' }],
        xName: 'x', yName: 'y',
        dataLabel: { visible: true, name: 'text', position: 'Inside'  },
        // Defines the gap to be left between the segments
        gapRatio: 0.04,
        }],
    title: 'Website visitor',
}, '#element');

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.

var piechart = new ej.charts.AccumulationChart({
    series: [
        {
            dataSource: [
                { x: 'Jan', y: 3, text: 'Jan: 3' }, { x: 'Feb', y: 3.5, text: 'Feb: 3.5' },
                { x: 'Mar', y: 7, text: 'Mar: 7' }, { x: 'Apr', y: 13.5, text: 'Apr: 13.5' },
                { x: 'May', y: 19, text: 'May: 19' }, { x: 'Jun', y: 23.5, text: 'Jun: 23.5' },

            xName: 'x',
            yName: 'y'
        }
    ],
    textRender: (args: IAccTextRenderEventArgs) => {
        if (args.text.indexOf('Others') > -1) {
            args.color = 'red';
            args.border.width = 1;
        }
    },
    pointRender: (args: IAccPointRenderEventArgs) => {
        if ((args.point.x as string).indexOf('Others') > -1) {
            args.fill = '#D3D3D3';
        }
    },

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.

var data = [

Customization

Individual points can be customized using the pointRender event.

var piechart = new ej.charts.AccumulationChart({
    series: [
        {
            dataSource: [
                { x: 'Renewed', y: 18.20, text: 'Renewed 18.20%' }, { x: 'Subscribe', y: 27.3, text: 'Subscribe 27.3%' },
                { x: 'Support', y: 55.9, text: 'Support 55.9%' },{ x: 'Downloaded', y: 76.8, text: 'Downloaded 76.8%' },
                { x: 'Visited', y: 100, text: 'Visited 100%' }
            ],
            type: 'Funnel',
            gapRatio: 0.08,
            xName: 'x',
            yName: 'y'

    pointRender: (args) => {
        if ((args.point.x).indexOf('Downloaded') > -1) {
            args.fill = '#f4bc42';
        }
        else {
            args.fill = '#597cf9';

Modes

The Funnel chart supports both Standard and Trapezoidal modes of rendering. The default value of the funnelMode is Standard.

Standard

The Standard funnel mode follows the traditional funnel shape, with the width continuously narrowing down to a point at the bottom.

var chart = new ej.charts.AccumulationChart({
    series: [{
        type: 'Funnel',
        dataSource: [{ x: 'Renewed', y: 18.20, text: 'Renewed 18.20%' },
        { x: 'Subscribe', y: 27.3, text: 'Subscribe 27.3%' },
        { x: 'Support', y: 55.9, text: 'Support 55.9%' },
        { x: 'Downloaded', y: 76.8, text: 'Downloaded 76.8%' },
        { x: 'Visited', y: 100, text: 'Visited 100%' }],
        xName: 'x', yName: 'y',
        //Width of the funnel will be 100% of the chart area
        width: '60%',
        //Height of the funnel will be 100% of the chart area
        height: '80%',
        dataLabel: { name: 'text', visible: true, position: 'Inside' },
        funnelMode: 'Standard'
        }],
    title: 'Website visitor',
}, '#element');

Trapezoidal

The Trapezoidal mode is a modified funnel shape where the width narrows, but features a flattened or parallel section near the top, creating a trapezoidal appearance. This mode helps compare different data points more clearly while maintaining a funnel-like structure.

var chart = new ej.charts.AccumulationChart({
    series: [{
        type: 'Funnel',
        dataSource: [{ x: 'Renewed', y: 18.20, text: 'Renewed 18.20%' },
        { x: 'Subscribe', y: 27.3, text: 'Subscribe 27.3%' },
        { x: 'Support', y: 55.9, text: 'Support 55.9%' },
        { x: 'Downloaded', y: 76.8, text: 'Downloaded 76.8%' },
        { x: 'Visited', y: 100, text: 'Visited 100%' }],
        xName: 'x', yName: 'y',
        //Width of the funnel will be 100% of the chart area
        width: '60%',
        //Height of the funnel will be 100% of the chart area
        height: '80%',
        dataLabel: { name: 'text', visible: true, position: 'Inside' },
        funnelMode: 'Trapezoidal'
        }],
    title: 'Website visitor',
}, '#element');
