[mapserver-users] CLASS visualization with different attribute value

[Simone Frigerio]

Thanks for support, Steve.
In the middle I tried also the expression:
CLASS
 NAME "PROVA7"
 GROUP "group7"
 EXPRESSION /0_2_0_4_5|1_2_3_4_5/
 STYLE
     SYMBOL "vertical-DF"
     SIZE 10
....

It is working. Is it conceptually the same?
Thanks.
