A specification like this
works perfectly giving something like
I would like to use the
sep option to shift the arrow in the same way but without the need for an arrow tip at the beginning.
If I write
I obtain a shifted arrow tip but the line supporting it starts with the arrow tip. Adding
. at the beginning does not help.
The question is: is there an arrow tip name indicating "no tip"? If such tip name existed I could use it to mark the start of the arrow line.
Alternatively: is there a better way to shift the arrow tip using tip specifications?
- by defining a new arrow tip you can control the extent of the tip.
- by drawing the arrow in two steps you can draw a
10ptlong and then the rest; very unsatisfactory.
- by using decorations one can position items, including an arrow tip, in any position. I would prefer to have an arrow tip specification.
Given TikZ 3 offer such powerful ways to modify the style of the tip (color, scale, slant, line style, bending etc) the absence of a shifting option / null-tip feels like an important omission.
