Gnuplot / Ghostscript create a table of content

I'm developing a Java application that processes information and that info has to be saved as graphs in a PDF file. I have 60 graphs as output, all with a different title.

What is an easy way to make a table of contents from all the graphs based on their title? Is there a command that can do this? Or do I have to use pdfmarks?

I can't find anything about this on the internet because if I use the words table of contents, I just get the table of contents of gnuplot/ghostscript itself.

You can generate the PDF using Latex and then use the epslatex terminal in gnuplot to generate the figures. You can write a script which generates the Latex document.

The gnuplot script:

set term epslatex color size 3,2 font 6
set output "figure1.eps"
#
set title 'Title of figure1'
#
plot sin(x)
#
exit

This generates an EPS file named figure1.eps and a Latex file named figure1.tex which embeds the EPS.

The the following Latex can in turn embed figure1.tex into a document:

\documentclass{article}

\usepackage{graphicx}
\usepackage{color}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage[mathcal]{euscript}

\begin{document}

\listoffigures

\begin{figure}
\centering
\include{figure1}
\caption[Description of figure1 as it appears on the list of
figures]{Caption of figure1.}
\end{figure}

\end{document}

Using the \listoffigures command a list of figures will be generated. You might need to run Latex a couple of times before the table appears. Then use dvipdf to export to PDF. The result should look like this:
