Hi,
I created a layer that renders pie chart with 4 classes.
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
