You may want to give the orgtbl-aggregate package a try.
(Available on http://melpa.org,
documentation here: https://github.com/tbanel/orgaggregate)
It creates the following table:
#+BEGIN: aggregate :table "grades" :cols "Precis count()"
| Precis | count() |
|---------+---------|
| A- | 7 |
| A | 7 |
| B | 2 |
| B+? A-? | 1 |
| B+ | 4 |
#+END:
Read it as:
- the "aggregate" function
- uses the "grades" table,
- groups rows with the same "Precis" value
- and "counts()" rows in each group.
There is a wizard to create it:
- M-x org-insert-dblock:aggregate
- C-c C-x i aggregate
You may add an ASCII-art plot by hitting:
C-c " a
#+BEGIN: aggregate :table "grades" :cols "Precis count()"
| Precis | count() | |
|---------+---------+---------|
| A- | 7 | WWWWWWW |
| A | 7 | WWWWWWW |
| B | 2 | WW |
| B+? A-? | 1 | W |
| B+ | 4 | WWWW |
#+TBLFM: $3='(orgtbl-ascii-draw $2 0 7 7)
#+END:
Have fun
