Thanks Steve, I can't use CLASSITEM since each class uses a different attribute
I tried with these 2 regex and I still have 4 slices. EXPRESSION ([cri] ~ '/[0-9]/') EXPRESSION ([cri] ~ '/./') "Lime, Steve D (DNR)" <steve.l...@state.mn.us> 2013-01-03 12:22 A "steve.tout...@inspq.qc.ca" <steve.tout...@inspq.qc.ca> cc "mapserver-users@lists.osgeo.org" <mapserver-users@lists.osgeo.org>, "mapserver-users-boun...@lists.osgeo.org" <mapserver-users-boun...@lists.osgeo.org> Objet RE: [mapserver-users] RE null value renders in pie chart How about using a regex instead: CLASSITEM ?cri? CLASS EXPRESSION /./ ?

The problem is some classes are render in the pie even if there is no data (null). That means I always have 4 slices in the pie. How can I remove the slices with null value? I tried using EXPRESSION without success. I specified > 0 since I think "is not null" is not supported CLASS NAME "Cri" EXPRESSION ([cri] > 0) STYLE SIZE [cri] COLOR 215 48 39 END END thanks for your help, Steve _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
