I simulated DPPC60%-DMPC40% +1AFO model membrane with Gromacs 4.5.4 and now I'm in analyzing step. I wanted to calculate area per lipid headgroup and bilayer thickness of the membrane so I used GridMAT-MD and I got output files (.dat file format). I can use Gnuplot in order to visualize .dat output file of membrane bilayer thickness  but I have problem using Xmatrix viewer, distributed as part of the Matpack ++ Numerics and Graphics Library. I get confused installing matpack. Now I want to know if I can use Gnuplot to visualize my area per lipid .dat files and if anyone have experience using Xmatrix in this way, I will be grateful to be noticed step by step with a simple explanation . It should be noted that I have Xmatrix viewer (matpack) installation guidance  (downloaded from matpack website) but I seems too complicated for me to be performed.

Or does anyone know any other program which I can use instead of matpack?

Thanks in advanced
