Bivariate legend

[Stephen Lime]

Best performance would be seen with a single item classification. You can
certainly use logical expressions to do the same thing at runtime.

  for example ([ITEM1] eq 5 and [ITEM2] > 14.9)

Hi MapServers!

I was wondering if anyone has tried to implement in a mapserver
application a layer with a bivariate classification, i.e. a
classification where a class is defined by a combination of two
attribute items? 
One way would be obviously to create a new field in the dbf attribute
table, that combines the two items in one unique value. 
Are there other ways?

TIA, Michael
