Hello liben89,

Thank you for posting in our community. Please take a look at the attached picture. It shows  in the Properties tab of the WebChart all the client side events available for handling and custom logic. Also you can switch (upper arrow) and see what are the server side events available for the control. Regarding runtime rotation  I would advise you to put the chart, a dropdown from which to choose around which Axis you want to rotate, a numeric editor provider to choose how many degrees to rotate and a button which to do the postback. Handle the button click server event and rotate the chart. Please also take a look at http://help.infragistics.com/Help/NetAdvantage/WinForms/2011.2/CLR2.0/html/Chart_Rotate_3D_Charts.html where it is explained how to set rotation.  You can also see the rotating samples in our online sample browser -http://www.infragistics.com/products/aspnet/chart/
