Thank you Andrea, I didn't know that statements such as "if" and
"maximum" are available and can be used just like any programming language.
if I've understood correctly your problem, I think you can use the
following expression in order to display a label (e.g. the aircraft
id) only for the first (i.e. having the minimum timestamp value) and
the last (i.e. having the maximum timestamp value) point for each
aircraft id:
if("TIMESTAMP" = maximum("TIMESTAMP","AC_ID") OR "TIMESTAMP" =
minimum("TIMESTAMP","AC_ID"), "AC_ID",'')
Anyway, once I discovered the marker attributes first and last vortex
the problem was solved.
