Florian, In my previous email to you, I indicated what is currently existing in Root for displaying x(i),y(i),value(i) The new Root class TPainter3DAlgorithms recently added in the system and replacing the previous class TLego has all the functionality to do what you want, but it still requires a user interface on top of it. I take this opportunity to announce that Olivier Couet is now joining the ROOT team. Olivier had been working with us on the PAW system for many years and he will take care of the 2-d and 3-d graphics in ROOT. Olivier's first task has been to implement TPainter3DAlgorithms. He could implement a 3-d graph class using TPainter3DAlgorithms for painting.
