enhancing Legend

[Milo van der Linden]

Hello list,

First of all Jacolin, thanks for the response.

I managed to "fake" a legend title by adding an empty class item as the 
topmost class for the layer I create the thematic legend for. This class 
item has no properties other then a name containing the text: "-- This 
is my legend --"

Works good enough for me!
