Gnuplot2TightPDF

Gnuplot is a widely known script based free plotting program. This script (gpt2pdf) makes it possible to generate pdf figures with 2D LaTeX maths on top of it by including psfrag replacements directly as comments in the gnuplot file. The resulting pdf file doesn't contain any extra white-spaces around it and as such can be comfortably included in any (pdf)LaTeX file.

Requires:
Python 2.4 - 2.7, LaTeX and the system commands ps2epsi and epstopdf which comes in with any ghostscript installation.
