The following should Org-babel alternative should work. 1) ensure org-babel in installed on your system, and gnuplot is activated. ;; Org-babel (require 'org-babel-init) (require 'org-babel-gnuplot) 2) Name your table with a #+tblname: just before the start of your table line, e.g. #+tblname: formulation-viscosities | your table contents | go right here | 3) create a gnuplot code block, which takes your table as an argument and plots it to a file, notice `:var' and `:file' the header arguments #+begin_src gnuplot :var data=formulation-viscosities :file ~/Desktop/test.jpg set terminal jpg transparent nocrop enhanced font arial 8 set xlabel 'Temperature (C)' set ylabel 'Viscosity (cP) set title 'Formulation Viscosities' plot "$data" with lines #+end_src WRT: the ugliness of gnuplot to file, I've wrestled with this myself and I know exactly what you mean. Currently I try to use svg or png images when exporting to html, and for pdf I use the gnuplot tikz terminal [2]. Gnuplot in combination with tikz results in *beautiful* plots, which render and resize well. However it took me hours to get everything configured, so it may not be for everyone.

John & Eric, Another approach, which I use and which doesn't require using the development version of gnuplot for the tikz support, is to generate encapsulated postscript files: set terminal postscript eps enhanced 20 set output "graph.eps" for instance. Then, if I need bitmap images, I use "convert" from ImageMagick to create these from the EPS files with the required density (depending on intended use, whether screen display or printing), as in convert -quality 95 -density 300 graph.eps graph.png With EPS, you can get very nice looking text, especially with the "enhanced" gnuplot set terminal option and the result is size independent.

I use a number of methods to generate graphs and diagrams and gnuplot is definitely one of my favourites. For the adventurous, there's a great blog: http://gnuplot-tricks.blogspot.com/ Put gnuplot together with org-mode and org-babel and it's yet another piece in the puzzle that leads to an incredibly powerful desktop analysis and publishing system!

Asymptote is unrelated to pgf. IMHO, it is far more powerful (i.e. 3D functionality) but admittedly less integrated into LaTeX (that's why org-babel is god sent). > However my most common graphical need is to display data read in from an > external file or from the command line, which I believe is orthogonal to > the main asymptote functionality. Asymptote can read and write text and XDR files. I'm not sure about the command line thing. Regards, -- Nicolas ^ permalink raw reply [flat|nested] 19+ messages in thread

Alan, I don't use gri. I have had a quick look at it and it should be possible (for others, not me :() to create an org-babel interface for this. If you have any elisp knowledge, you could try starting from one of the existing language implementations. You could also try to use the support for sh in org-babel but you'd have to get the table data into a file first. Others may have more reasonable suggestions, however...

If this is something you're interested in, you could start by making a copy of org-babel-gnuplot.el, and then search/replace gnuplot/gri, and you'll be most of the way there. The gnuplot file already has support for dropping tables to tab-separated files, and then placing the paths to those files into the body of code blocks, which may be sufficient for table support in gri -- although having not heard of gri before this email I can't say for sure.

After all, a lot of Org users (will) need some kind of plotting solution, so this kind of discussion is naturally useful to them. After all, disregarding unwanted e-mails is definitely easier than getting to see the off-list ones ;-) Štěpán ^ permalink raw reply [flat|nested] 19+ messages in thread

I needed/wanted a tool to produce publication quality graphs. Gnuplot is great, and I have used it in the past, to make tide graphs. In my experience, controls of the details of the graph were less accessible to me, and the graphs I produced were pretty rough edged. GRI has worked very well for me for monthly tide graph calendars, with good control of parameters. GNUPLOT is fantastic for quick, and what I felt were rough and ready plots. GRI is easily installed on Ubuntu installs, and a gri mode for emacs makes it easier. I will try the suggestions you made to work out a babel solution for gri plots. Thanks for the suggestions, Alan ^ permalink raw reply [flat|nested] 19+ messages in thread
