Hello everyone,

I was thinking that it would be nice to have a visual representation
of clocked time. It could give you a quick overview of when and how
long you had been working on a particular task.

For example, you have a subtree like this:

** very important task
   CLOCK: [2009-10-03 Sat 22:02]--[2009-10-03 Sat 23:21] =>  1:19
   CLOCK: [2009-10-04 Sun 23:53]--[2009-10-05 Mon 02:10] =>  2:17
   CLOCK: [2009-10-06 Tue 14:10]--[2009-10-06 Tue 14:50] =>  0:40
   CLOCK: [2009-10-07 Wed 21:25]--[2009-10-08 Thu 00:21] =>  2:56
   CLOCK: [2009-10-13 Tue 01:52]--[2009-10-13 Tue 02:52] =>  1:00
   CLOCK: [2009-10-13 Tue 20:58]--[2009-10-13 Tue 23:32] =>  2:34
   CLOCK: [2009-10-14 Wed 23:20]--[2009-10-15 Thu 00:55] =>  1:35
   CLOCK: [2009-10-16 Fri 14:14]--[2009-10-16 Fri 14:53] =>  0:39
   some text here

You press a combination of keys and get a table like this:

|---------------+-----+-----+-----+-----+-----+-----+-----+------|
| Week Starting | Mon | Tue | Wed | Thu | Fri | Sat | Sun | tt,h |
|---------------+-----+-----+-----+-----+-----+-----+-----+------|
|    2009-09-28 |     |     |     |     |     |  79 | 137 |  3.6 |
|    2009-10-05 |     |  40 | 176 |     |     |     |     |  3.6 |
|    2009-10-12 |     | 214 |  95 |     |  39 |     |     |  5.8 |
|---------------+-----+-----+-----+-----+-----+-----+-----+------|

The table contains total number of clocked minutes for every day and
total number of hours for every week.

If I could write such a thing in Emacs lisp, I would do that.  But
unfortunately I can't.  So, I wrote a python script and small function
in lisp to call it.  I am posting them here in hope that it might be
useful for someone.

Org-mode is an excellent thing. Thank you!

Best regards,
Gennady Trafimenkov
