Code blocks give you much more direct access to gnuplot, which I find generally makes gnuplot learning/debugging much easier. see http://orgmode.org/manual/Working-With-Source-Code.html add something like this to your config (org-babel-do-load-languages 'org-babel-load-languages '((gnuplot . t))) then try something like the following Best -- Eric --=-=-= Content-Type: text/x-org Content-Disposition: inline; filename=simple-gnuplot-tests.org ** simple gnuplot tests #+results: some-more-gnuplot | 1 | 1 | | 2 | 4 | | 3 | 9 | | 4 | 16 | | 5 | 25 | | 6 | 36 | | 7 | 49 | | 8 | 64 | #+TBLFM: $2=$1*$1 #+begin_src gnuplot :var data=some-more-gnuplot plot "$data" #+end_src #+results: Plotting data points from a table could look like this: #+tblname: basic-plot | x | y1 | y2 | |-----+------------+------------| | 0.1 | 0.425 | 0.375 | | 0.2 | 0.3125 | 0.3375 | | 0.3 | 0.24999993 | 0.28333338 | | 0.4 | 0.275 | 0.28125 | | 0.5 | 0.26 | 0.27 | | 0.6 | 0.25833338 | 0.24999993 | | 0.7 | 0.24642845 | 0.23928553 | | 0.8 | 0.23125 | 0.2375 | | 0.9 | 0.23333323 | 0.2333332 | | 1 | 0.2225 | 0.22 | #+begin_src gnuplot :var data=basic-plot :exports code :file basic-plot.png set title "Putting it All Together" set xlabel "X" set xrange [0:1] set xtics 0,0.1,1 set ylabel "Y" set yrange [0.2:0.5] set ytics 0.2,0.05,0.5 plot data u 1:2 w p lw 2 title 'x vs. y1', \ data u 1:3 w lp lw 1 title 'x vx. y2' #+end_src #+results: [[file:basic-plot.png]] --=-=-= Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Michael Gilbert writes: > Hi =E2=80=94 > > There is a single line in the OM manual (currently on p32) which reads: > > line Specify an entire line to be inserted in the Gnuplot script. > > I am trying to insert a couple of horizontal reference lines in a > simple plot.
