textext? Did it work? On my computer it hangs after approximately 13
plots. The suggested option is to use "sometxt" now.

input is the default anyway

\useGNUPLOTgraphic[mybeautifulcurves][1] should work (I have to check
- perhaps I forgot to prevent from loading the file once more).

Looks as if \useGPgraphic shortcuts would be needed ;)

Sure. With md5 checksums new gnuplot runs should be prevented ... (if
I ever come so far to know how to implement it or if Hans kindl offers
a solution ;)

Even better (faster) if you have a compiled version of plots and only
include PDF ;)

I just finished dummy parsing of font switches (terminals should
implement set font "fontname,fontsize"), I have to implement palettes
and then the first phase of the terminal will be ready (still missing
are the binary images and more clever handling of palettes)

The only thing I would like to sort out before officially releaing it:
some new things come and will come to the gnuplot core (like
transparency). I'm thinking about replacing the syntax from something
like
gp_put_text(x, y, gp_align_left, \sometxt{...}, ...)
to something more general:
gp_put_text("align=left,x=...,y=...")
which basically means any number of optional parameters and
consequently no problems with backward compatibility later if

That should go to gnuplot CVS then.

And t-gnuplot is/will be on modules.contextgarden.net (Hans might add
it to distribution once it's ready/stable etc.)
That one is not so clean yet. I need to implement changing the color &
similar with \setupGNUPLOT[colorset=...,pointset=...,size=...,linewidth=...,
...]
