   2 # Report generation for plot-sgpdd
   3 # ================================
   4 #        The plot-sgpdd script is used to generate csv file and
   5 # instructions files for gnuplot from the output of sgpdd-survey.pl script.
   6 #
   7 #        The plot-sgpdd also creates .scr file that contains instructions
   8 # for gnuplot to plot the graph. After generating .dat and .scr files this
   9 # script invokes gnuplot to display graph.
  10 #
  11 # Syntax:
  12 # $ sgpdd-survey > log_filename
  13 # $ plot-sgpdd <log_filename>
  14 # [Note: 1. This script may need modifications whenever there will be
  15 #           modifications in output format of sgpdd-survey.pl script.
  16 #        2. Gnuplot version 4.0 or above is required.]
