[Qgis-user] Offsetting rotated labels proportionate to variable angles/rotations

[Tony Shepherd (FarmMaps NZ)]

Hi All

 

Simple question, but I am not sure how best to word it. Since we all love
maps, I have a diagram below.

1.	Create some points along a polyline. Easy using "Points along
Gemoetry"
2.	Display and label the points and put a rotation on the labels and
justify as needed (middle right in this case)

 

What I want to do is shift the label out from the point slightly. That's
easy if using Offset X and Y, but it does exactly as expected and moves them
X and Y, NOT accounting for the angle.

 

I'm guessing I would need to use Data Defined X and Y and do some
trigonometry using the angle and distance to calculate the new preferred
label position.  Does anybody have code to do this?

 

A simple workaround I did use was to just pad a few spaces to the end of the
label (ie "FIELD NAME" || '    ')

 



Cheers

Tony
