[Mapserver-users] GetLegendGraphic questions

[bartvde at xs4all.nl]

Hi list,

I have some questions about the GetLegendGraphic operation in Mapserver.

I have a layer in my MAP file which has 5 classes, but when performing a
GetLegendGraphic request I only get an image of the last class defined.
Should I not get an image of all classes?

Also, how do you get the "text labels" for the specific classes, e.g.
"0-20%" next to the symbols?

Maybe I am missing something in my LAYER definition?

This is the request I am using:
http://myserver/cgi-bin/mapserv.exe?map=/ms4w/apps/zulte/map/zulte_server.map&layer=kwelder_2000&version=1.1.1&request=GetLegendGraphic&format=image/png

This is my LAYER definition:

      WMS_TITLE "2000_kwelder"
      WFS_TITLE "2000_kwelder"
      WMS_ABSTRACT "2000_kwelder"

    	NAME "41-60%"
    	COLOR 255 151 41
    END
    CLASS
    	EXPRESSION (([Kwelder_to] > 60) AND ([Kwelder_to] <= 80))
    	NAME "61-80%"
    	COLOR 217 95 13
    END
    CLASS
    	EXPRESSION (([Kwelder_to] > 80) AND ([Kwelder_to] <= 100))
    	NAME "81-100%"
    	COLOR 153 54 5
    END
  END

Thanks in advance for any info on this subject.

Best regards,
