gnuplot

Taking results of my data ...earlier it was not coming out well since the overhead was more than the test app exe time and i was geting really lazy improving it but now with a few changes in the nature of test apps this are working fine..got a great link for gnuplot :
Some good tips on how to have it directly as eps, how to display grids etc .good for beginners and for people with short term memory like me :) :

Also if you would like two figures to be laser-printed on the same page, you may use the following shell script. Create file cat2 , below, and make the file executable by typing: unix% chmod +x cat2

      # cat2: Shell script for putting two Gnuplot plots on one page
     echo %! > g.ps
     echo gsave >> g.ps
     echo 0 400 translate >> g.ps                  # for Gnuplot plots
     cat $1 | sed -e "s/showpage//" >> g.ps
     echo grestore >> g.ps
     echo gsave >> g.ps
     echo 0 090 translate >> g.ps                  # for Gnuplot plots
     cat $2 >> g.ps
     lpr -Phudsonlp1 g.ps

To combine two PostScript figures (plot1.ps and plot2.ps) on one page:

            cat2  plot1.ps  plot2.ps
