Pyramid in EJ2 TypeScript Accumulation chart control

13 Dec 202414 minutes to read

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

import { AccumulationChart, PyramidSeries} from '@syncfusion/ej2-charts';
AccumulationChart.Inject(PyramidSeries);

let chart: AccumulationChart = new AccumulationChart({
    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: 'Japan', y: 25, text: 'Japan 25%' },
            { x: 'Germany', y: 27, text: 'Germany 27%' }],
        xName: 'x', yName: 'y',
        }],
}, '#element');

Mode

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

import { AccumulationChart, PyramidSeries} from '@syncfusion/ej2-charts';
import { pyramidData } from './datasource.ts';
AccumulationChart.Inject(PyramidSeries);

let pyramidchart: AccumulationChart = new AccumulationChart({
    series: [{
        type: 'Pyramid',
        dataSource: pyramidData,
        xName: 'x', yName: 'y',
        pyramidMode: 'Surface',
        }],
}, '#element');

Size

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

import { AccumulationChart, PyramidSeries} from '@syncfusion/ej2-charts';
import { pyramidData } from './datasource.ts';
AccumulationChart.Inject(PyramidSeries);

let chart: AccumulationChart = new AccumulationChart({
    series: [{
        type: 'Pyramid',
        dataSource: pyramidData,
        xName: 'x', yName: 'y',

        //Width of the pyramid will be 100% of the chart area
        width: '60%',

        //Height of the pyramid will be 100% of the chart area
        height: '80%',
        }],
}, '#element');

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.

import { AccumulationChart, PyramidSeries} from '@syncfusion/ej2-charts';
import { pyramidData } from './datasource.ts';
AccumulationChart.Inject(PyramidSeries);

let pyramidchart: AccumulationChart = new AccumulationChart({
    series: [{
        type: 'Pyramid',
        dataSource: pyramidData,
        xName: 'x', yName: 'y',
        // Defines the gap to be left between the segments
        gapRatio: 0.2,
        }],
}, '#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.

import { AccumulationChart, PyramidSeries, IAccPointRenderEventArgs } from '@syncfusion/ej2-charts';
import { pyramidData } from './datasource.ts';
AccumulationChart.Inject(PyramidSeries);
let pyramidchart: AccumulationChart = new AccumulationChart({
    series: [{
        type: 'Pyramid',
        dataSource: pyramidData,
        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

    }]
});
pyramidchart.appendTo('#element')

Customization

Individual points can be customized using the pointRender event.

import { AccumulationChart, PyramidSeries, IAccPointRenderEventArgs } from '@syncfusion/ej2-charts';
import { pyramidData } from './datasource.ts';
AccumulationChart.Inject(PyramidSeries);
let pyramidchart: AccumulationChart = new AccumulationChart({
    series: [{
        type: 'Pyramid',
        dataSource: pyramidData,
        xName: 'x', yName: 'y',
        gapRatio: 0.04
    }],

    pointRender: (args: IAccPointRenderEventArgs) => {
        if ((args.point.x as string).indexOf('India') > -1) {
            args.fill = '#f4bc42';
        }
        else {
            args.fill = '#597cf9';
        }
    },
}, '#element');
