[mapserver-users] Displaying repeated values in label

[thomas bonfort]

remove the MINDISTANCE keywords from your labels, they prevent
duplicate labels from appearing closer than the specified distance
(i.e. 600 in your case) which depending an your image size can mean
that your 0.0 is only displayed once.
