A suggestion would be to try out Brian Toby's EXPGUI for
Windows and Linux which also comes with the "liveplot"
viewer.
Example screen dumps on using this are given in the
previous post on Spherical Harmonics PO correction using
GSAS. And the EXPGUI homepage is at:

ftp://ftp.minerals.csiro.au/pub/xtallography/ccp14/ccp/web-mirrors/briantoby/programs/crystallography/software/expgui/expgui_intro.html
Liveplot/EXPGUI also has some very nice options for changing
display characteristics such as colours and size and type of
markers, etc.
