[Cartoweb-users] strange scalebar behaviour

[Oliver Christen]

Hi

the values displayed in the scalebare are automaticaly handled by mapserver.
the only parameters you can changes are the ones specified in the mapfile 
specifications
http://mapserver.gis.umn.edu/docs/reference/mapfile/scalebar
the rest is handled by mapserer itself.
