If gnuplot doesn't fail with it, it probably means that it works OK ;)
"Helvetica" seems to work OK here:
http://dl.contextgarden.net/misc/gnuplot-context.zip
(Usually I get dozens of error messages when applying something new,
at least "memory limit exceeded" if everything else happens to work by
accident ;)
The most funny part was when practiacally all the labels were missing
on one plot before I figured out that
\setupbodyfont[somefont,14pt]
\switchtobodyfont[some other font]
doesn't work at all without defining bodyfontenvironment.
Thank you very much again! The .tex file is still in its "pre-alpha"
state, but at least I was able to "finalize" the terminal with a clean
syntax ;)

yes ... once I manage to convince the developers that the difference
between these two plots might be relevant enough to justify an
additional driver:
http://gnuplot.sourceforge.net/demo_4.1/enhancedtext.html
http://dl.contextgarden.net/misc/enhancedtext.pdf
(I hope that Patrick will not be reading this before I manage to
remove the files again ;)
