[OS X TeX] How to plot functions with PGF and TeXShop ?

[Peter Lichtner]

Sorry! I take that back---it only worked because I had first run from  
the shell with pdflatex --shell-escape pgf-test.tex. Running TeXShop  
in a 'clean' directory gives incorrect results with gnuplot not found:

loading : Context Support Macros / PDF (2004.03.26)
)sh: line 1: gnuplot: command not found
sh: line 1: gnuplot: command not found
sh: line 1: gnuplot: command not found
