Hallo Werner,

See __gnuplot_open_stream__.m:30
What does "[prog, args] = gnuplot_binary ()" give you in octave?

What about "which gnuplot" in a terminal?

./configure found gnuplot? See for example my config.log:

~/src/octave-build$ grep -C1 gnuplot config.log
configure:8332: result: gs
configure:8371: checking for gnuplot
configure:8387: found /usr/bin/gnuplot
configure:8398: result: gnuplot
configure:8444: checking for less
--
  Default pager:               less
  gnuplot:                     gnuplot

--
ac_cv_prog_GHOSTSCRIPT=gs
ac_cv_prog_GNUPLOT=gnuplot
ac_cv_prog_GPERF=gperf
--
GNULIB__EXIT='0'
GNUPLOT='gnuplot'
GPERF='gperf
