Re: st: Graphs display on a page

[Christina Wei <christinaw1211@gmail.com>]

Assuming you want to break down item_id into 9 groups (assuming no id
duplicates and you are okay with sorting your groups by  low to high)
here is what I would do:

xtile item_id_groups = item_id, nq(9)
twoway scatter scatter avg_price quote_date, by(item_id_groups).

That should give you the 3x3 plot you are looking for.  Hope this helps.
