Hi Nicol: Do you you have a sample mapfile that showed your approach? Since 
CHART and ANNOTATION are both layer types that implies multiple layers. --Steve

Hello,

I am trying to understand how labeling/annotation with layer type
'chart' for the individual slices e.g. of a PIE/BAR chart would work (

I have tried to set a LABELITEM on layer level, a LABEL block within
the CLASS section, a TEXT property in the CLASS block but none of my
attempts show any labels.
In earlier versions of Mapserver I have used the ANNOTATION layer type
to get labels but this type is now deprecated for 7.x versions.
Any ideas?
Thank you very much.

Nicol
