pgplot is very powerful and you can configure it in almost any way,
but for that I am
afraid you will have to use the "low" level pgplot routines for this.
They are not difficult to use.
As far as I can remember, last time I used gnuplot was some 10 years
ago, pgplot was much
more powerful and versatile than gnuplot. For this purpose I would
recomend to stick with
pgplot (unless again gnuplot has improved so much that is better than pgplot)
Have a look at http://www.astro.caltech.edu/~tjp/pgplot/subroutines.html
Of course, another option is to use plplot which is very similar to
pgplot and more up to date.
Here is the program that will do the trick for you:
#!/usr/bin/env perl
use PDL;
use PDL::Graphics::PGPLOT::Window;
use PDL::Graphics::LUT;
use PGPLOT;
$w=pgwin('/xserve');
pgscr(0,1,1,1);
pgscr(1,0,0,0);
pgslct(1);
pgsvp(0.1,0.9,0.15,0.9);
pgswin(170,290,log10(1020),log10(7));
pgsci(8);
pgslw(4);
pgbox('BCNST',0,0,'BCNSTL',0,0);
pgsci(4);
pgslw(1);
pgsls(4);
pgbox('G',0,0,'G',0,0);
$w->hold;
pgsci(2);
pglab('T, T\ddew\u (K)','p (hPa)',$dates[$idate]);
Note the pgsci commands which change color, pgslw which changes line width and
pgsls which changes line style
