org: Agenda column view
10.8 Using column view in the agenda
====================================
Column view (Column view) is normally used to view and edit
properties embedded in the hierarchical structure of an Org file. It
can be quite useful to use column view also from the agenda, where
entries are collected by certain criteria.
‘C-c C-x C-c (org-agenda-columns)’
Turn on column view in the agenda.
To understand how to use this properly, it is important to realize
that the entries in the agenda are no longer in their proper outline
environment. This causes the following issues:
1. Org needs to make a decision which ‘COLUMNS’ format to use. Since
the entries in the agenda are collected from different files, and
different files may have different ‘COLUMNS’ formats, this is a
non-trivial problem. Org first checks if the variable
‘org-agenda-overriding-columns-format’ is currently set, and if so,
takes the format from there. Otherwise it takes the format
associated with the first item in the agenda, or, if that item does
not have a specific format (defined in a property, or in its file),
it uses ‘org-columns-default-format’.
2. If any of the columns has a summary type defined (Column
attributes), turning on column view in the agenda will visit all
relevant agenda files and make sure that the computations of this
property are up to date. This is also true for the special
‘CLOCKSUM’ property. Org will then sum the values displayed in the
agenda. In the daily/weekly agenda, the sums will cover a single
day; in all other views they cover the entire block. It is vital
to realize that the agenda may show the same entry _twice_ (for
example as scheduled and as a deadline), and it may show two
entries from the same hierarchy (for example a _parent_ and its
_child_). In these cases, the summation in the agenda will lead to
incorrect results because some values will count double.
3. When the column view in the agenda shows the ‘CLOCKSUM’, that is
always the entire clocked time for this item. So even in the
daily/weekly agenda, the clocksum listed in column view may
originate from times outside the current view. This has the
advantage that you can compare these values with a column listing
the planned total effort for a task—one of the major applications
for column view in the agenda. If you want information about
clocked time in the displayed period use clock table mode (press
‘R’ in the agenda).
4. When the column view in the agenda shows the ‘CLOCKSUM_T’, that is
always today’s clocked time for this item. So even in the weekly
agenda, the clocksum listed in column view only originates from
today. This lets you compare the time you spent on a task for
today, with the time already spent (via ‘CLOCKSUM’) and with the
planned total effort for it.
