I am trying to rotate a 2D histogram, which is drawn in “COLZ” option. I follow an example of rotation by using TTree in a poster and store the two variables m_x and m_y into TTree. Then I try to rotate data in TTree, but I failed.
I put my code in the attachment. Could you please give me some suggestion on how to rotate data by using TTree?
Thank you very much for your help!
