Map marker rotation

I try to rotate the markers on the map and noticed a strange behaviour.

This is the rotation at 0° angle
0

after rotation to +90°
+90

and the rotation to -90°
-90

I expected the arrow to show to left or right on a 90° angle. How is the rotation calculated?

On Rotating to 180° the arrow will show to the bottom left corner rather than showing straight down :thinking:

Anybody got some experience using the rotation of the markers?

Thanks for any help and greetings,
Marcel

You need to set the angle in radians, so 360° = 2π = 6.283185 rad

Thank you very much :smiley: this was almost driving me crazy :laughing:
