using more plotting area for a lattice plot
Hi Group,
For the plot below, are there other ways I can use more of the
plotting space. I've tweaked the parameters I know of.
I could also put the plot titles inside the plot if there is a way to
do that. Thanks for your input. Regards, Juliet

Storing a Selected Option in DB
OK, thanks to Kelly I got my options_for_select in a select_tag
helper method to use a Ruby range as a value. Now when the user makes
a selection from that list, I can''t figure out why the result doesn''t
get stored in the database.
The line in the _form looks like this:
<%= select_tag(:month, options_for_select((0..12).to_a)) %>
Pops up an option menu.

{ :prompt => "Please Select..."} %>
which sets a model field in the params hash.
If I want to do the same for a non-model field,
