I spend most of my time plotting data, but unfortunately I haven’t found a decent solution for my plotting needs. At the moment, the most powerful and pleasant library I found that performs plotting is matplotlib. The results are stunning, but I mostly spend my time fighting with the library when trying to do simple things like having an arrow as I want. SImilar programs like R and gnuplot produce visually less appealing results, and they are not GUI based.

On the other hand, programs like xmgrace (or better) allow direct manipulation of the plotted objects and direct feedback, but they fail on two important points:

  1. if my dataset (normally stored in csv files) changes for some reason, I have to reimport it and perform the manipulations again, by hand
  2. once I obtain a nice plot setup, the only way I have to recreate the plot is to use a graphical, interactive program. I would like to have the possibility to run a command line utility on my csv files and get the .pdf as a result, with no human intervention.

I still have to find something that provides me both worlds, and it has an affordable price. Ideally, I would need an interactive GUI program (a la Origin) to generate matplotlib-based python scripts.

Does anyone have any hints on software that could address my needs on OSX (preferably) or Linux ?

    You may want to check out Igor Pro. It’s quite old, and quirky but it provides the most advanced plotting system I’ve found yet on the Mac. You can modify anything graphically, at a command line or in script files. The most powerful feature (IMO) is the ability to automatically generate a script to recreate a figure or to use a figure to create a script that generates figures like (in style etc.) a particular figure. I use Igor for all publication figures I produce.

    Data is stored in “waves” (translation: vectors) which encapsulate data and information about the delta between data points (e.g. time step). Figures reference waves as their data source. When you update a wave (e.g. by re-importing a CSV file and specifying that the data overwrite specific waves), all figures that reference that wave are automatically updated.

    You can create “layouts” which are page-layouts containing multiple graphs. These layouts are also automatically updated whenever any of the figures in the layout are updated (see above). You can add drawing/text/annotations to either graphs or layout.s

    Be warned: Igor Pro’s scripting language is something like the bastard child of VB and Matlab. It makes my eyes bleed. It makes me pray to whatever God that the pain just end. But the entire system is so powerful that it’s worth it.
