splot and #+PLOT keyword

splot and #+PLOT keyword

[Eric S Fraga]

Hello,

a question/problem regarding the #+plot: keyword.

I am trying to plot out some data where the table looks like this:

#+begin_src org
  ,#+plot: ind:(6 7) deps:(1) with:"linespoints pt 7" set:"logscale xy" type:3d
  |     1 |   81 |      5 |      0 |   2.27 |     0.9729848950975623 |   0.019370016994566613 | 0.0 |

#+end_src

I have tried a variety of directives for the #+PLOT: keyword but none
give me what I want.  I would like to plot column 1 (dependent variable)
versus columns 6 and 7 (independent variables) in 3d.  (don't ask ;-))

I have also tried:

   #+plot: ind:6 deps:(7 1) ...

but in all cases I seem to be getting somewhat random data plotted,
possibly columns 2 versus 3 and 4, which makes no sense except that
maybe the "|" table column separator is being retained in the data file
created.  Is there any way to stop the data file from being deleted
after plotting?  I can inspect the *gnuplot* buffer but cannot see the
actual data.

2d plots work just fine, by the way.

thank you,
eric

Have you tried looking at the produced gnuplot script? It goes in a temp file
so it's a bit of a pain, but that's my fallback method when I'm really confused :-)

Hi Nick,

The issue appears to be the data that are also placed in a temp
file.  These are data extracted from the table, i.e. the relevant
columns.  The file disappears... so I guess I will go diving into the
code and make sure the file sticks around so I can debug.

Thank you,
eric

Looking at the code, 3d plotting does not support plotting individual
selected columns, it would appear. :-(

I think I'll stick to using src blocks instead, which is what I've been
doing for years, for 3d plots.

Sorry for the noise and thanks again.
