Subject: [UMN_MAPSERVER-USERS] Chloropleth maps with Mapserver

I am currently evaluating the capabilities of MapServer to retrieve
data from a Postgresql database and display it on a chlorpleth map.
For instance, I have data like:

Area      IndicatorValue

Area 1     10
Area 2    20
Area 3  15
Area 4  20
etc etc

Each region will be represented by a color, depending on what the
value is in the "IndicatorValue" column. The users need to be able to
select (dynamically) how many color regions will be displayed on the
map, and what the value range of each color is.

I have searched high and low through the archives, and Google, but
can't seem to find a definitive answer, or better yet, and example of
how this can be done with Mapserver.Any pointers would be most
welcome.

Best regards,
JPP
