David,

I think that option should indeed work in the class expressions. Do you have
a more complete example (map file)?

Best regards,

Tamas

David,

I think that option should indeed work in the class expressions. Do you have a

I have been playing around with the new cluster functionality a little bit.

I am looking for way to classify the clusters based on their feature counts.  
E.g. larger circles for clusters of > 10 features and even larger circles for 
clusters of > 100 features.

Because Cluster:FeatureCount returns a string, the below expression can 
evaluate to True for values like "109"

("[Cluster:FeatureCount]" < "11")

Does anyone have any suggestions?

Maybe I am just misusing Clusters...

Thanks,

David.
