To render a pyramid series, use the series type as Pyramid and inject PyramidSeries module using the AccumulationChart.Inject(PyramidSeries) method.

index.js
index.html
var chart = new ej.charts.AccumulationChart({
    width: '600px',
    series: [{
        type: 'Pyramid',
        dataSource: [{ x: 'Australia', y: 20, text: 'Australia 20%' },
            { x: 'France', y: 22, text: 'France 22%' },
            { x: 'China', y: 23, text: 'China 23%' },
            { x: 'India', y: 24, text: 'India 24%' },

            { x: 'Germany', y: 27, text: 'Germany 27%' }],
        xName: 'x', yName: 'y',
        dataLabel: { name: 'text', visible: true, position: 'Inside' },
        }],

Mode

The Pyramid chart supports linear and surface modes of rendering. The default type of the pyramidMode is linear.

index.js
index.html
var pyramidchart = new ej.charts.AccumulationChart({
    series: [{
        width: '600px',
        type: 'Pyramid',
        dataSource: [
            { x: 'Australia', y: 20, text: 'Australia 20%' },
            { x: 'France', y: 22, text: 'France 22%' },

            { x: 'Germany', y: 27, text: 'Germany 27%' },
        ],
        xName: 'x', yName: 'y',
        dataLabel: { visible: true, name: 'text', position: 'Inside'  },
        pyramidMode: 'Linear',

Size

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

index.js
index.html
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' },
        }],

Gap between the segments

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

index.js
index.html
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.

index.js
index.html
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' },
                { x: 'Jul', y: 26, text: 'Jul: 26' }, { x: 'Aug', y: 25, text: 'Aug: 25' },
                { x: 'Sep', y: 21, text: 'Sep: 21' }, { x: 'Oct', y: 15, text: 'Oct: 15' },
                { x: 'Nov', y: 9, text: 'Nov: 9' }, { x: 'Dec', y: 3.5, text: 'Dec: 3.5' }],
            dataLabel: { visible: true, name: 'text', position: 'Outside' },
            groupTo: '11',
            xName: 'x',
            yName: 'y',
            explode: true,
            //Specifies the distance of the point from the center during explode, which takes values in both pixels and percentage
            explodeOffset: '10',

            //If set true, all the points in the series will get exploded on load
            explodeAll: false,

            //Specifies index of the point, to be exploded on load
            explodeIndex: 2
        }
    ],
    textRender: (args) => {
        if (args.text.indexOf('Others') > -1) {
            args.color = 'red';
            args.border.width = 1;
        }
    },
    pointRender: (args) => {
        if ((args.point.x).indexOf('Others') > -1) {
            args.fill = '#D3D3D3';
        }
    },
}, '#element');

Customization

Individual points can be customized using the pointRender event.

            groupTo: '11',
            xName: 'x',

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