Step 2: Add the reference to your project by right click on the solution explorer of your project.

Step 3: Write the below code in which event you want to draw Pie Chart.

private void CreateChart()

//Create some dummy Data

Random random = new Random();

for (int pointIndex = 0; pointIndex < 10; pointIndex++)

"Series1"].Points.AddY(random.Next(20, 100));//Set the chart type

Chart1.Series["Series1"].ChartType = SeriesChartType.Pie;// Set the bar width

Chart1.Series["Series1"]["PointWidth"] = "0.5";// Show data points labels

Chart1.Series["Series1"].IsValueShownAsLabel = true;// Set data points label style

Chart1.Series["Series1"]["BarLabelStyle"] = "Center";// Show chart as 3D

Chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = true;// Draw chart as 3D Cylinder

Chart1.Series["Series1"]["DrawingStyle"] = "Cylinder";

Add Namespace:- 

using System.Web.UI.DataVisualization.Charting;
