I'm working on a map that has a lot of points in a small area, so I'm adding lines from my labels to their points using a Geometry generator in the symbol designer. The problem I'm having is that the lines always come from the bottom left corner of the label.

How do I get them to come from the part of the label that is closest to the point?

I'm using the following Expression and really don't have a clue where to go from there.

    make_line( make_point( $x,$y), make_point( "X","Y"))
  • Have you considered using the easy_label plugin? – Ian Turton Feb 22 '18 at 9:00
  • I have tried it, and had some problems with it. it seems like it always wants to add some extra kinks in the lines. and I cant seem to get rid of them. – Troy Buerge Feb 23 '18 at 14:20
  • but you could use it's label points to draw your own line – Ian Turton Feb 23 '18 at 14:25
  • I'll have to look into that. I'm still learning how to do some of that stuff, so don't always think of everything. – Troy Buerge Feb 23 '18 at 15:46
  • I tried that, but when I used the geometry generator I couldn't even get the lines to draw. – Troy Buerge Feb 23 '18 at 16:04

Changing the label alignment will change which corner of the label is located at the defined point.

enter image description here

Set up data-defined label alignment

  1. Add two new text fields, Align_H and Align_V
  2. Fill Align_H with the desired horizontal alignment of each label: left or right. Fill Align_V with the desired vertical alignment: bottom or top.
  3. Use these fields to control alignment under label properties. enter image description here
  • I'm getting somewhere now. I can draw a line based on a condition in the geometry generator expression area. What i would like to do is be able to get the bounds of my label now. something like this: 'CASE WHEN "Y" < $y THEN make_line(make_point("X", "Y_max" ),$geometry) END' Where "Y_Max" is the the top of the label, or "X_max" is the the right side. – Troy Buerge Mar 1 '18 at 15:36
  • If you want help getting the bounds of the label, I think that merits being a separate question. – csk Mar 5 '18 at 21:08
