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,
Luis A. Perles
