# Pgfplot

PgfPlot is a package which let you do the same things as gnuplot but directly inside your latex file. And this has a lot of advantages:

- no additional file
- no conversion from eps or ps or png to the pdf
- the quality is really improved
- the picture text has the same font as the rest of the document
