Hi Org-Moders,
I've been using Org-Mode quite a bit, but I'm afraid I'm not an advanced
user. I'm trying to generate burndown charts [1] which basically follow
coding progress over a bounded period of time (an iteration).
I started by generating a file for each iteration:
<snippet_of_org_file>
* Tasks in iteration
- [[file:list_1.org]]
- [[file:list_2.org]]
#+tblname: test_chart
| Day | Expected | Actual |
|-----+----------+--------|
| 0 | 4 | 4 |
| 1 | 3 | 4 |
| 2 | 2 | 1 |
| 3 | 1 | 0 |
| 4 | 0 | 0 |
</snippet_of_org_file>
list_1.org and list_2.org contain a total of 4 tasks for this time
period (tagged with :iteration1:). The table is updated manually at
present. "Day" is an index to the days in the time period, with work
always starting on day 1; "Expected" is the number of tasks expected to
be remaining on that day; "Actual" is the number of tasks actually
remaining. I then use org-babel/gnuplot to plot the chart as explained
on a previous post [2].
It seemed logical to try to generate the table automatically. I can use
org-mode's spreadsheet's facilities for generating all the days in the
table and I can even use date arithmetic to get dates for a day index.
As you can imagine, the bit I'm really stuck with is how to populate the
"Actual" and "Expected" columns.
I've read a little bit about agenda views, and they seem to do a lot of
what I want, but unfortunately the lisp is not entirely obvious for a
newbie such as me. My questions are:
- is there an org-mode function that computes the total number of tasks
marked with a given tag in this file and any other files it includes?
- is there an org-mode function that computes the total number of tasks
marked with a given tag and marked as CLOSED on a given day in this file
and any other files it includes?
I was wondering if you could give me some pointers on how to go about
finding or even creating these functions as I failed to find anything
obvious. Even a "give up, its not trivial" would do, so I can at least
stop searching.
Many thanks for your time.
Marco

Marco, try this:

*** burndown
#+srcname: burndown
#+begin_src sh :session
cd ~/org
MONTH=$(date +%m)
DAYS_DONE=$(egrep -A1 "\* DONE" gca.org | egrep -o "CLOSED: \[[0-9]{4}-$MONTH-[0-9]{2}" | cut -c 10- | sort -u)
echo "day expected actual"
for DAY in $DAYS_DONE
do
NEXT_BY_DAY=$(egrep -A1 "\* NEXT" gca.org | egrep -o "SCHEDULED: <$DAY" | wc -l)
DONE_BY_DAY=$(egrep -A1 "\* DONE" gca.org | egrep -o "CLOSED: \[$DAY" | wc -l)
echo $DAY $NEXT_BY_DAY $DONE_BY_DAY
done
#+end_src
#+results: burndown
