Well they have wildly different values, so plotting all three together means you can't see any fluctuations, so you might as well just look at the averages... If you want all three with fluctuations, then you'll need to play with the plotting program's functionality for representations and axes (for xmgrace). See http://www.gromacs.org/Documentation/How-tos/Graphing_Data for various ideas on plotting.
