Hi,</font><font size=3 face="Times New Roman"> </font><font size=3 face="Arial"><br>
I created a layer that renders pie chart with 4 classes.</font><font size=3 face="Times New Roman">
</font><font size=3 face="Arial"><br>
<br>
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.</font><font size=3 face="Times New Roman">
</font><font size=3 face="Arial"><br>
How can I remove the slices with null value?</font><font size=3 face="Times New Roman">
</font><font size=3 face="Arial"><br>
<br>
I tried using EXPRESSION without success. I specified > 0 since I think
"is not null" is not supported</font><font size=3 face="Times New Roman">
</font><font size=3 face="Arial"><br>
CLASS</font><font size=3 face="Times New Roman"> </font><font size=3 face="Arial"><br>
NAME "Cri"</font><font size=3 face="Times New Roman">
</font><font size=3 face="Arial"><br>
EXPRESSION ([cri] > 0)</font><font size=3 face="Times New Roman">
