Pie chart

To render a pie series, inject the PieSeries3D module using CircularChart3D.Inject(PieSeries3D) method.

var circularchart = new ej.charts.CircularChart3D({
    series: [
        {
            dataSource: [
                { x: 'Jan', y: 3 },  { x: 'Feb', y: 3.5 }, 
                { x: 'Mar', y: 7 },  { x: 'Apr', y: 13.5 },
                { x: 'May', y: 19 }, { x: 'Jun', y: 23.5 }, 
                { x: 'Jul', y: 26 }, { x: 'Aug', y: 25 },
                { x: 'Sep', y: 21 }, { x: 'Oct', y: 15 }
            ],
            xName: 'x',
            yName: 'y'
        }
    ],
    tilt: -45,
    legendSettings: { visible: false }
}, '#element');

Radius customization

By default, the radius of the pie series will be 80% of the size, which is the minimum of the 3D Circular Chart’s width and height. You can customize this by using the radius property of the series.

var circularchart = new ej.charts.CircularChart3D({
    series: [
        {
            dataSource: [
                { x: 'Jan', y: 3 },  { x: 'Feb', y: 3.5 }, 
                { x: 'Mar', y: 7 },  { x: 'Apr', y: 13.5 },
                { x: 'May', y: 19 }, { x: 'Jun', y: 23.5 }, 
                { x: 'Jul', y: 26 }, { x: 'Aug', y: 25 },
                { x: 'Sep', y: 21 }, { x: 'Oct', y: 15 }, 
                { x: 'Nov', y: 15 }, { x: 'Dec', y: 15 }
            ],
            xName: 'x',
            yName: 'y',
            radius: '100%'
        }
    ],
    tilt: -45,
    legendSettings: { visible: false }
}, '#element');

Various radius pie chart

You can assign different radii to each slice of the pie by fetching the radius from the data source and using it with the radius property in the series.

var circularchart = new ej.charts.CircularChart3D({
    series: [
        {
            dataSource: [
                { x: 'Belgium', y: 551500, r: '110.7' },
                { x: 'Cuba', y: 312685, r: '124.6' },
                { x: 'Dominican Republic', y: 350000, r: '137.5' },
                { x: 'Egypt', y: 301000, r: '150.8' },
                { x: 'Kazakhstan', y: 300000, r: '155.5' },
                { x: 'Somalia', y: 357022, r: '160.6' },
                { x: 'Argentina', y: 505370, r: '100' }
            ],
            xName: 'x',
            yName: 'y',
            radius: 'r',
            dataLabel: {
                visible: true, position: 'Outside',
                name: 'x'
            },
            innerRadius: '20%'
        }
    ],
    tilt: -15,
    title: 'Countries compared by population density and total area',
    legendSettings: { visible: true },
    enableAnimation: true
}, '#element');

Donut chart

To achieve a donut in the pie series, customize the innerRadius property of the series. By setting a value greater than 0%, a donut will appear. The innerRadius property takes value from 0% to 100% of the pie radius.

var circularchart = new ej.charts.CircularChart3D({
    series: [
        {
            dataSource: [
                { x: 'Jan', y: 3 },  { x: 'Feb', y: 3.5 }, 
                { x: 'Mar', y: 7 },  { x: 'Apr', y: 13.5 },
                { x: 'May', y: 19 }, { x: 'Jun', y: 23.5 }, 
                { x: 'Jul', y: 26 }, { x: 'Aug', y: 25 },
                { x: 'Sep', y: 21 }, { x: 'Oct', y: 15 }, 
                { x: 'Nov', y: 15 }, { x: 'Dec', y: 15 }
            ],
            xName: 'x',
            yName: 'y',
            innerRadius: '40%'
        }
    ],
    tilt: -45,
    legendSettings: { visible: false }
}, '#element');

Text and fill color mapping

The text and the fill color from the data source can be mapped to the 3D Circular Chart using pointColorMapping in the series and name in the data label, respectively.

var circularchart = new ej.charts.CircularChart3D({
    series: [
        {
            dataSource: [
                { x: 'Jan', y: 3, fill: '#498fff', text:'January' }, 
                { x: 'Feb', y: 3.5, fill: '#ffa060', text: 'February' },
                { x: 'Mar', y: 7, fill: '#ff68b6', text: 'March' }, 
                { x: 'Apr', y: 13.5, fill: '#81e2a1', text: 'April' }
            ],
            xName: 'x',
            yName: 'y',
            pointColorMapping: 'fill',
            dataLabel: {
                visible: true,
                name: 'text'
            }
        }
    ],
    tilt: -45,
    legendSettings: { visible: false }
}, '#element');

Customization

Individual points in pie chart can be customized using the pointRender event.

var circularchart = new ej.charts.CircularChart3D({
    series: [
        {
            dataSource: [
                { x: 'Jan', y: 3 }, 
                { x: 'Feb', y: 3.5 },
                { x: 'Mar', y: 7 }, 
                { x: 'Apr', y: 13.5 }
            ],
            xName: 'x',
            yName: 'y'
        }
    ],
    tilt: -45,
    legendSettings: { visible: false },
    pointRender: (args) => {
        if ((args.point.x).indexOf('Apr') > -1) {
            args.fill = '#f4bc42';
        }
        else if ((args.point.x).indexOf('Mar') > -1) {
            args.fill = '#DE3D8A';
        }
        else if ((args.point.x).indexOf('Feb') > -1) {
            args.fill = '#F7523F';
        }
        else {
            args.fill = '#597cf9';
        }
    }
}, '#element');
