Thank you for the reply @phenom . But I have already tried it.
The main problem is my representation is bigger than my track length in the segment so the representation is coming out of the track
when I use your strategy inside the track it's perfectly fine but the representation which is lying outside the track is still visible.
It seems this issue appears in v13
in v13.2 onwards the lane Names ("A","B")
are placed in the body of the track or
- if too big- disappear.
What I can suggest in this case (as workaround for v13) is
to set the horizontal track line color to white
Thank you @simulator for the answer and the time. I will try to ask how I can represent and yes i see that with a white background it works fine. or else i will try to execute the same in a higher version. thanks once again
