You don't need the commas between the individual "commentschars" (i.e. a
comma then is also regarded as marking the start of a comment line), but
that shouldn't break your plot.

Your example data plots fine here (gp5.2pl2) too. What is the problem
exactly? Could it be you just don't see the plot because gnuplot
immediately "quit"s after doing it? ;-)
