@Carl Love Indeed dear Carl, I previously mentionned that in my question, which is that I can't figure out why "L" does not variate, and even in this situation the "plot" function should give 3 horizontal lines, i.e the same value of "L" all over the given tickmarks but different value for the dimension "d" and "r" , isn't it ? (I'll shift "l" to "L" for more readibility as you said)

@J4James  So did you see my script sir ?

@J4James  The question is reformulated now.
