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.
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.
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.]
