ok - got zoom to work - another question

[Joseph Norris]

David,

Thank you for your insight into my scenario.  You have perceived correctly
on what I am trying to do. I agree with your point about dot-density maps.
This scenario is only meant to be a "dog-and-pony" show and so the dots
would have no real earth relevance other than to say - wow within this zip
polygon there are 5 teachers, 6 teachers, etc.... ( very small data set - no
more than 0-20 teachers per zip area ).  I have successfully been able to
show a list of teachers by polygon - in another bit of html by the map.

  The lengthy <elaborate kludge> that you mention is something I would like
to avoid due to the nature of the project. So that leaves me with the
open-ended question to all - what suggestions do any and all have with
regard to the last part of what I am trying to accomplish - namely - allow
the user to zoom into a polygon and see some representation of what's
there - a label of the actual number of teachers? I am opened to that but at
this point in my mapserver education, I am limited in my understanding of
Labeling. Can a label be placed within the minscale/maxscale scenario so
that when you zoom in you see the label and when you zoom out it disappears?

Please bare with me - I have made a lot of progress in the past three days -
a lot more than I thought I would and I would like to see this through to
the end.

Thanks again.

Joseph,

Does this accurately describe what you are trying to do?

You have a map of California ZipCodes and you have classified them so
that ZipCodes with teachers of interest are colored differently than
ZipCodes where there are no teachers of interest.

Once a user zooms to minimum scale, you want the ZipCode polygons with
teachers of interest to be symbolized with a 'dot' for each teacher.  It
looks like you have successfully set up two complimentary
scale-dependent layers.
