<span style="font-size:10.0pt;font-family:"Arial","sans-serif""><br>
Hi,</span> <span style="font-size:10.0pt;font-family:"Arial","sans-serif""><br>
I created a layer that renders pie chart with 4 classes.</span> <br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif""><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.</span>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif""><br>
How can I remove the slices with null value?</span> <br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif""><br>
I tried using EXPRESSION without success. I specified > 0 since I think "is not null" is not supported</span>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif""><br>
CLASS</span> <span style="font-size:10.0pt;font-family:"Arial","sans-serif""><br>
NAME "Cri"</span> <span style="font-size:10.0pt;font-family:"Arial","sans-serif"">
<br>
EXPRESSION ([cri] > 0)</span> <span style="font-size:10.0pt;font-family:"Arial","sans-serif"">
<br>
STYLE</span> <span style="font-size:10.0pt;font-family:"Arial","sans-serif"">
<br>
SIZE [cri]</span> <span style="font-size:10.0pt;font-family:"Arial","sans-serif"">
<br>
COLOR 215 48 39</span> <span style="font-size:10.0pt;font-family:"Arial","sans-serif"">
<br>
END</span> <span style="font-size:10.0pt;font-family:"Arial","sans-serif"">
<br>
END</span><br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif""><br>
thanks for your help,</span> <span style="font-size:10.0pt;font-family:"Arial","sans-serif"">
