You may want to consider a slightly different approach. It may (or
maynot) be relevant depending on your context.
First, denormalize your table into a "fact table" (which is handy when
dealingwith cubes):
#+name: data
| date | type | q |
|------------------+-------+-----|
| [2014-04-27 Sun] | Sys | 125 |
| [2014-04-28 Mon] | Sys | 102 |
| [2014-04-29 Tue] | Sys | 115 |
| [2014-04-27 Sun] | Dia | 88 |
| [2014-04-28 Mon] | Dia | 88 |
| [2014-04-29 Tue] | Dia | 88 |
| [2014-04-27 Sun] | Pul | 78 |
| [2014-04-28 Mon] | Pul | 86 |
| [2014-04-29 Tue] | Pul | 85 |
| [2014-04-27 Sun] | Sugar | 92 |
| [2014-04-28 Mon] | Sugar | 92 |
| [2014-04-29 Tue] | Sugar | 95 |
Then using a package named "org-aggregate" (on Melpa) you can derivean
aggregated table:
#+name: aggr
#+BEGIN: aggregate :table data :cols "type vcount() vmean(q) vmax(q)
vsdev(q);f3"
| type | vcount() | vmean(q) | vmax(q) | vsdev(q);f3 |
|-------+----------+----------+---------+-------------|
| Sys | 3 | 114 | 125 | 11.533 |
| Dia | 3 | 88 | 88 | 0 |
| Pul | 3 | 83 | 86 | 4.359 |
| Sugar | 3 | 93 | 95 | 1.732 |
#+END:
If you want to rotate this table, apply a transposition on it(provided
by the same package):
#+BEGIN: transpose :table "aggr"
| type | | Sys | Dia | Pul | Sugar |
| vcount() | | 3 | 3 | 3 | 3 |
| vmean(q) | | 114 | 88 | 83 | 93 |
| vmax(q) | | 125 | 88 | 86 | 95 |
| vsdev(q);f3 | | 11.533 | 0 | 4.359 | 1.732 |
#+END:
You can sort the "data" table on dates without changing theaggregation.
