And no, using an opaque background for my label to mask away the call out line doesn’t really hack it. I know the label box isn’t being calculated at the time the polygon is being rendered so the answer is probably ’no’ but maybe someone else has a clever idea to make may lollipops work when labels are south (or east or west for that matter) of the feature being labelled?<br><br>Thanks!<br><br>Regards<br><br>Tim<br><br><br><br>—<br><br><br><KartozaNewLogoThumbnail.jpg><br><br><br><br><br><br><br>Tim Sutton<br><br>Co-founder: Kartoza<br>Ex Project chair: QGIS.org<br><br>Visit <a href="http://kartoza.com" target="_blank">http://kartoza.com</a> to find out about open source:<br><br>Desktop GIS programming services<br>Geospatial web development<br>GIS Training<br>Consulting Services<br><br>Skype: timlinux <br>IRC: timlinux on #qgis at <a href="http://freenode.net" target="_blank">freenode.net</a><br><br>I'd love to connect.
