Hi all I want to create a pie chart for some data. The problem that I'm facing
is that i'm not getting any errors when I test the layer using shp2img;
however, I just get a white image. This is my mapfile: MAP EXTENT
-20037508 -20037508 20037508 20037508 SIZE 400 400 IMAGETYPE
PNG LAYER NAME "Survey" TYPE CHART CONNECTIONTYPE OGR
CONNECTION "MSSQL:server=myserver;database=data;uid=me;pwd=key" DATA
"SELECT Option, COUNT(*) AS RESULT FROM Survey GROUP BY Option" PROCESSING
"CHART_TYPE=pie" PROCESSING "CHART_SIZE=30" STATUS ON CLASSITEM
'Option' CLASS EXPRESSION '1' NAME "one" STYLE
SIZE [RESULT] COLOR 255 244 237 END END CLASS
EXPRESSION '2' NAME "two" STYLE SIZE [RESULT]
COLOR 255 217 191 END END CLASS EXPRESSION '3'
NAME "three" STYLE SIZE [RESULT] COLOR 255 186
140 END END CLASS EXPRESSION '4' NAME "Four"
STYLE SIZE [RESULT] COLOR 255 186 0 END
END END END Any ideas of what could be missing in my mapfile? Thanks
