Lately I have been using org-mode to manage the data for a study I'm doing for my research project. I primarily use the spreadsheet features to do all the calculations and then use gnuplot to plot the final result. For all the basic plotting it works great, but I am having trouble when I want error bars in my plot. To demonstrate my point here is a small example. > #+PLOT: title:"My plot" ind:1 deps:(2) type:2d with:xyerrorlines > | Abscissa (X) | Ordinate (Y) | X low edge | X high edge | Y low edge | Y high edge | > |--------------+--------------+------------+-------------+------------+-------------| > | 60 | 1.1140741 | 0020 | 0100 | 1.1699508 | 1.0680423 | > | 150 | 1.1187818 | 0100 | 0200 | 1.1593492 | 1.0855438 | > | 350 | 1.1193459 | 0200 | 0500 | 1.1331885 | 1.1086636 | > | 600 | 1.1029173 | 0500 | 0700 | 1.0940769 | 1.1121185 | > | 850 | 1.0841388 | 0700 | 1000 | 1.0676310 | 1.1000886 | > | 1250 | 1.0358938 | 1000 | 1500 | 1.0127586 | 1.0586916 | > | 2000 | 0.89370079 | 1500 | 2500 | 0.88014981 | 0.925 | This gives me an error like this, > gnuplot> plot '/tmp/org-plot30213YHV' using 1:2 with xyerrorlines title 'Ordinate (Y)' > Not enough columns for this style I have tried changing the "#+PLOT:" line to say this, > #+PLOT: title:"My plot" ind:1 deps:(2 3 4 5 6) type:2d with:xyerrorlines But that doesn't work either. I think the problem is org-plot doesn't recognise that when plotting with error bars, gnuplot expects more than two columns of data. So a command like this should be sent to gnuplot, > plot '/tmp/org-plot30213YHV' using 1:2:3:4:5:6 with xyerrorlines title 'Ordinate (Y)' In fact typing this on the gnuplot terminal actually generates the desired plot! So I thought maybe I should try org-babel. So I tried something like this, > #+srcname: plot-data-w-err > #+begin_src gnuplot > set title 'My plot' > plot 'data-table' using 1:2:3:4:5:6 with xyerrorlines title 'Ordinate (Y)' > #+end_src and gave my table a name like this, #+tblname: data-table But that didn't behave as I was expecting it to. I think I don't quite understand how to pass a table as an input to a source block. I was hoping someone on the list could either help me understand how babel uses tables as inputs, or pass the correct command to gnuplot with org-plot. BTW, org-mode is phenomenal. Loving every bit of it.
