TGraph

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
