Size

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

        {
            public string xValue;
            public double yValue;
        }

Neck Size

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

        {
            public string xValue;
            public double yValue;
        }

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.

gap.cs

<ejs-accumulationchart id="container" title="Mobile Browser Statistics">
            <e-accumulationchart-legendsettings visible="false">

            {

                new FunnelChartData { xValue = "Chrome", yValue = 37 },
                new FunnelChartData { xValue = "UC Browser", yValue = 17 },
                new FunnelChartData { xValue = "iPhone", yValue = 19 },
                new FunnelChartData { xValue = "Others", yValue = 4  },
                new FunnelChartData { xValue = "Opera", yValue = 11 },
                new FunnelChartData { xValue = "Android", yValue = 12 },
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class FunnelChartData
        {
            public string xValue;
            public double yValue;
        }

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.

<ejs-accumulationchart id="container" title="Mobile Browser Statistics">

            {

                new FunnelChartData { xValue = "Chrome", yValue = 37 },
                new FunnelChartData { xValue = "UC Browser", yValue = 17 },
                new FunnelChartData { xValue = "iPhone", yValue = 19 },
                new FunnelChartData { xValue = "Others", yValue = 4  },
                new FunnelChartData { xValue = "Opera", yValue = 11 },
                new FunnelChartData { xValue = "Android", yValue = 12 },
            };
            ViewBag.dataSource = chartData;
            return View();
        }
        public class FunnelChartData
        {
            public string xValue;
            public double yValue;
        }

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.
