Subject: Fixed g_sgangle legends.
X-Git-Url: http://biod.pnpi.spb.ru/gitweb/?a=commitdiff_plain;h=dd0ddd7d3ef42ad940d6c592fc1f821589b63f78;p=alexxy%2Fgromacs.git

Fixed g_sgangle legends.

There were no legends previously, and questions are often asked
about the interpretation of the data.  This commit adds proper
s0 and s1 legends in XmGrace format.
