Hi,
I am trying to do a layer of count by zip code. I use a style of circle with
the count number as the label which is palced in the center of the circle.
Please see the SLD below. It works fine when the map is loaded, but when I zoom
in the map, the label is not centered in the circle anymore. Instead, the label
position is outside of the circle.
Is there a way to solve this problem?
