However because of a bug in the apparatus software the first and the second measurement are always unreliable, therefore I want to skip them. This is an example: 1 #unreliable 1.5 #unreliable 3 #reliable 3.1 #reliable 2.9 #reliable #start of next 5 measurements: 3 #unreliable 3.1 #unreliable 3.5 #reliable 3.4 #reliable 3.6 #reliable Can anyone here show me how to do is from within Gnuplot? kind regards, Hugo
