Hi all,
bored during watching TV I played a little bit around with the shiny
dashboard-framework of R and made a small visualization tool of the
account balance and the register in R. It is of course a really rough
sketch, will be quite buggy, so suggestions and criticism is greatly
appreciated. Some aspects of the implementation are rather specified to
the way I use Ledger, eg my Account structure is at the max three
levels deep. That being said, have fun:

This is rather cool! One of the things I have missed since I switched from
TextMate to Vim is an interface to R. I had no time so far to work on it,
so projects like yours are greatly appreciated. Visualizing data gives
lots of insight, and R is extremely powerful (not to mention its potential
for statistical analysis...).
Some feedback:
- You'd better use quantity() get the numbers from Ledger (e.g.,
'%(quantity(amount))' instead of '%(amount)').
- For income accounts, it would be probably better to swap the signs
(or just take '%(abs(quantity(amount))').
- It would be nice to support multiple commodities, by adding an option to
choose a default commodity for the plots and by passing -X to Ledger.
- Many statisticians would frown upon pie charts (and for a reason). They
are widespread in finance and business, but I'd prefer to have an
option to see bar charts or dot charts.
- If you have a chance to try the Ledger plugin for TextMate, you may get
some inspiration for further charts (one thing I liked to draw was a
heat map of my net worth over time). The source code is here:
https://github.com/lifepillar/Ledger.tmbundle
and the R stuff is in Support/lib/r. I used ggplot2 for the plots.
I hope to see more Ledger/R stuff!
Life
