#    Input to GNUPLOT, causing it to read BLOCKS_DATA.TXT and
#    create a plot of blocks of data.
#
#    GNUPLOT can handle what it calls a "multi-data-set file".
#    This is simply the concatenation of several ordinary GNUPLOT
#    data files, with two blank lines between each set.
#
#    The user can thus keep several sets of data in one file,
#    and plot whichever one is of interest.
#
#    Notice that the indexing of data sets starts at 0, not 1.
#    So what we might think of as the third data set is indexed by 2.
