Hello,

I want to plot energy against variable from this table.

#+plot: title "Final energy vs nkpt" ind:5 deps:(6) type:2d with:points 
|       workdir       |   calcdir    |   volume    | iscl |        coa         
| variable |     energy     |
|---------------------+--------------+-------------+------+--------------------+----------+----------------|

I think the #+plot: invocation is correct for org-plot/gnuplot but when
run I just get "user-error: Current buffer has no process".

I appreciate any help offered.

Cheers,
