Hi Joythi,
Thank you for using Syncfusion product.
We can rotate the Tornado chart using Rotation property of the chart control. We can rotate the chart upto 90 degree, to view the chart rotation we must to set the chart in 3D mode.
Kindly review the code snippet.
//Setting chart in 3D mode
this.chartWebControl1.Series3D = true;
// Chart rotation
this.ChartWebControl1.Rotation = Int32.Parse(this.TextBox1.Text.ToString());
Please take a look at the sample and let me know if its helpful.
