Dear Rooters, from a scan in parameter space I have a function z(x,y), which I would like to plott. (with z-values of 100-400) Actually I dont wont to use a histogram as I dont wont scattering. (Or can this be switched off ?) But TGraph does only work for y(x), or is there a posibility to have z(x,y) ? Anyway, if I tryed to use a TH3F histogram, but than the "surf" draw option which works for TH2F does not seam to work. Probably there is an easy way which I just dont see. I would very much apreceate any help. Claus Horn
