I want to draw a custom arrow that connects two nodes. Unfortunately, I think this cannot be done with the arrows library:
Tikz provides convenient shapes for such a case, e.g., the signal arrow. But for some reason there appears to be no way to draw it along a path as an edge.
But how would I transform it such that it points from one coordinate to another?
My general idea would be to:
- Stretch the arrow, i.e. increase the distance between the head and the tail
- Rotate the arrow such that it actually points towards the target
What is the idiomatic way to stretch (a part of) and rotate an existing shape?
To begin with, I could actually live with only point 1, but it would be important that I do not stretch the tip and tail but only the "middle end".
