gnuplot development

you may fix this by drawing a white line where the upper border would be
located:

set arrow 1 from graph 0, 1 to graph 1, 1 nohead front linecolor rgb "white"

This is a workaround that doesn't work in some cases, like when the
upper border should instead be transparent, as it would be in some
other terminals. Is there a solution for that?

the 'system' command returns a string which used as the first argument in
a plot command will be interpreted as a filename - that's the way gnuplot
is instructed to read data from a file.
just tell gnuplot that 'GewMW' doesn't contain a filename but a numerical
value:
plot 1.*GewMW

Hi Thomas,
Thank you very much!
plot "star.dat"   using 7,  f(x) t "mean <x>" ,  1.*GewMW t "w.mean" w l
did the trick   =)

regards AP.

I have found a solution; as usual it is very simple:

unset view
splot "data" matrix with lines

re,
 wh

the 'textcolor' option for keys was introduced in version 4.4.

I never heard about it ... but these page describe a basic howto in gnuplot
no clue what language or what the data may look like.

I don't understand this language, but I  think that unfortunately this 
page describe an other ternary diagram..

according to google it is indonesian.

re,
 wh

I do not know these zonotopes/zonohedrons
but there is a "glass.dem" at http://gnuplot.sourceforge.net/demo_4.4/surface1.html
last entry is a mandelbrot. Since you can calculate the edges it
should be possible.

The difference in machines and OS versions is almost 100% certainly a 
red herring.  The real problem is bound to lie in the versions of 
underlying libraries your self-built version uses.

Unfortunately, none of those attachments made it to the mailing list. 
Configure.out in particular would have been absolutely crucial to see. 
Without it all I can offer is a guess: look at the startup-screen of 
your respective gnuplot binaries: what do they report as the terminal 
driver?  The output of "show version long" would be almost equally 
informative.

By having different terminals compiled in and used, for one thing.

Hi Jon,

include the command

exit

after the first plot.

Cheers,

Hernán
