Hi: I'd like to make a comment on TGraph. Suppose I declare a graph "gr" by: TGraph gr(10) This means allocate room for 10 points. Later on I do not fill points up to 10, say I just put 7 points into "gr".(this does happen in code because sometime the # of points inputed depends on sth else.) Then when I call gr.Fit(...), I think it will fit based on my 7 points and another 3 points at (0,0). Ofcourse we do not want to include those Zeros in the fitting. This is not critical, but not convenient for the user. Correct me if I am wrong? Thanks. Aihong
