[mapserver-users] Displaying repeated values in label

[Toni Martínez]

Hi all,
I am using MapServer version 5.6.1 reading data from Postgis.
One of the layers I am working with makes use of labels displaying data from
a Postgis column over a marker on the map. Everything seems to be working
fine but some data to be displayed on labels is 0.0 In such case, mapserver
only displays one marker with its label.
Because I need all markers and labels to be represented on that layer even
if values are the same, I have been trying some options that I read in
mapserver official docs like MINDISTANCE or FORCE or PROCESSING
"LABEL_NO_CLIP=ON" with no results.
Please take a look at my layer's code.
