Gnuplot output to PDF (via eps).

• First, make a gnuplot "plot" file which uses "postscript" terminal output
  Although the new gnuplot supports pdf terminal output - it doesn't seem as full featured as the eps/pdf output.
  The important terminal lines are as follows:
  set terminal postscript portrait enhanced color dashed lw 1 "DejaVuSans" 12
  set output "temp.ps"
  
• Next run gnuplot on your plot file:
  gnuplot temp.plot
• Then convert the eps to pdf:
  epstopdf temp.ps
• Then use pdfcrop to make sure the bounding box is aligned with the output:
  pdfcrop temp.pdf; mv temp-crop.pdf temp.pdf

• This can all be done via a script (eg: save it as gnuplotcrop):

  #!/usr/bin
  bn=`basename $1 .plot`
  gnuplot $bn.plot
  epstopdf $bn.ps
  pdfcrop $bn.pdf
  mv $bn-crop.pdf $bn.pdf
  

• Then, just run gnuplotcrop file.plot - make sure the output is defined as file.ps inside this file.
