Using the following code, can the red arrow and its text be inserted within a node at pos=.5 (beside the blue circle) of the blue line, instead of drawing it separately with a draw command

aligned pin
in my answer to one of your previous question? you can also use simplepin
. sorry, actually i don't understand your question well ...path picture
. However, I am struggling to understand what that should be good for.pin
for that. You don't need anything as fancy as thealigned pin
style though, just a normal one.aligned-pin
is based on one of previous op question. there are also shown, how to use simplepin
as i also mentioned in my comment. i thing that this question is duplicate.
