labeling - Label callouts in QGIS


Has anyone been using callout labelling with QGIS, either trunk or stable?


Used for clustered points. That means the point stays where it is, the label maybe moved if required and a leader (plain or pointed) shows the linkage between the label and the point.


How could I do it (you know what I mean, no coding....)?



Answer



You can do this without any coding but just to follow the points carefully...


1) Download & add Qgis plugin 'Easy Custom Labelling' from Qgis Official repository. Run the first part of the plugin, "generate centroids".


2) Label your layer using 'Labeling' tool & move overlapping labels manually (Using Label Move-Present at Labeling Toolbar) after toggoling editing mode.



3) after saving the necessary edits...run the 'Easy Custom Labelling' plugin and select 'generates Lines from Labels' button (This will create your desired Leader as a separate .shp file).


For safety, when the tool asks for a projection (CRS), use the same as the layer which is being labelled. Your mileage may vary if you choose another.....


Check the snap attached for further understanding...
