I am a newbie and I need to develop a web gis app, that have a capability to show a thematic layer dynamically based on users option from combo box.
I am using mapserver and pmapper. I want to have a plugin/function similar to queryeditor. Queryeditor unable to group all field's data in attribute table as well as giving a thematic display to the layer. This plugin also can't correctly querying text field, for numeric type it worked just fine.
I found out the runtime substitution in mapserver doc, but I am still confuse how to apply it in my pmapper.
For instance, I want to build a rainfall thematic. What should I do to make it automatically pick class style/color for all type of data within the chosen field.
Thanks in advance.
