Gentlemen,

I apologize for the noise. It seems that the problem is in another part of my code. If I cannot figure out by myself I will get back with more details. Thanks for the answers.

Hi,
I also looked closely at your data points, they match exactly the graphs produced.
I also tried to plot gp2 first and gp1 on top of it. All is fine again. I do not see the problem.
Note that your file "*Exp*" does not have a uniform formating and contained TABs,
I changed that, but that makes no changes: the graphs are the same and look fine.

Hello everybody,

I am having problems to display graphics using a line to conect the experimental points in ROOT. Ploting the same data with Grace and ROOT I can see that the line draw to conect points by ROOT is little above the line draw by the Grace. It seems to be a problem with ROOT because others programs like Origin and Excel agree with Grace resulting plot. I am running ROOT 5.22/00a compiled with GCC version 4.3.2 by myself using Gentoo automatic compilation script (portage+emerge) in Linux OS 32 bits. Please, could someone else confirm this problem?

Attached is a script to load some data to reproduce the results. Also, there are two screenshots attached showing what I am seeing.

Cheers,
