3.6.2 gnuplot diagrams

You can create gnuplot diagrams as normal images. pd2tex has support to automatically invoke gnuplot if there is a file whose name corresponds to missing image and ends in the extension .gnuplot. The file must contain gnuplot commands, but due to gnuplot's ability process inline data (file name '-' in plot command), can also contain the data itself.

Another way to create a gnuplot diagram is using gnuplot directive and include the gnuplot commands and data inline in your .pd file. For example:

  <<gnuplot: name-for-diag,,2: Legend for gnuplot diagram.
  set terminal postscript eps lw 3.0 24
  set nokey
  set xlabel "Dosímetros"
  set ylabel "Factor de sensibilidade"
  plot [0:10] [0:1.5] '-' using 1:($2/14.57) with errorbars
  # media 14.57, desvio padrao 0.98
  # num   Valor   Normalizado (mal, com f=med/N, deve ser f=N/med)
  1	14.29	.02
  2	14.39	.01
  3	13.56	.07
  4	14.78	.99
  5	14.15	.03
  e
  >>

Note how '-' was specified to include the data inline and last line is e to indicate the end of the data. Your data SHOULD start with set terminal postscript eps stanza. If this line is missing, it will be supplied with one using default arguments. If you do not want to use Latin 1 (ISO-8889-1) encoding, you should specify the desired encoding on the first line. See gnuplot(1) documentation for further information. The above would create output in Fig-4.
