I would like to draw a decoreted path starting at the anchor of one node and going in a specific direction for a specific distance.
I Found something like this:
\draw(node.north) -- (50:2cm);
This schould go a distance of 2cm starting at node.north and going in an angle of 50. However, this did node work in my case.
My code:
\draw[decorate,decoration={expanding waves, angle=65, segment length=8}] (stoer.north) -- (<???>);
The aim is to go straight 3cm up. So starting at stoer.north and ending 3cm above stoer.north (however maybe other directions should also be possible)
How could this work? I also tried something like
(stoer.north) -- (stoer.north shift (0,3));
