- Hi Dave!
-
- I have run up against this problem in the past when trying to make data
- tables of SEX vs. AGE, where I wanted AGE to be say, <18, 18-25, 26-30,
- etc., much as you want your dates to be 15Jun92-14Jul92, 15Jul92-14Aug92,
- etc., as I understand it. The only solution I was ever able to come up
- with was to create another column next to the AGE column, called "AGEGRP",
- where I used a lookup table to assign values based on which range the age
- fell into. For example:
-
- | A | B | C | D | E |
- --|------|-------|-------|-------|-------|
- 1 | AGE | AGEGrp| | lookup table |
- 2 | 15 | 1 | | 17 | 1 |
- 3 | 22 | 2 | | 25 | 2 |
- 4 | 21 | 2 | | 30 | 3 |
- 5 | 43 | 6 | | 35 | 4 |
- 6 | 17 | 1 | | 40 | 5 |
- 7 | 39 | 4 | | 45 | 6 |
-
- Where the formulas in column B would be fashioned after
- B2: @vlookup(A2,$table,1), and the range named "table" is
- D2..E7. Having done this, you can run /Data Table on the
- values in column B rather than column A, knowing that
- AgeGrp=1 means Age<18, AgeGrp=2 means Age is 18-25, etc.
-
- This same idea could be applied to your date dilemma.
- Use a formula to create a column of date values equal
- to the 15th of every month for the given year. Then use
- the same sort of scheme to look up a DateGrp variable
- and run your table on it.
-
- There may be a more succinct solution out there, but I haven't
- found it. Send me E-Mail if you want more help with this one.
-
- Have fun!
- Maria
