It might be very simple, but I cannot find the specific answer to this: how can I plot the first vs the last and the second to last columns in several files whose column number is variable? is there something like
plot "mydata.txt" using 1:-1?
I've already tried to use tail, but I don´t know hot to specifically use it, and couldn´t make this answer Count columns in csv in gnuplot work neither :(
Thanks!

But the total number of columns is variable in each file. I have to plot first column vs the two last ones... and I couldnt make your link work on these. Any idea why? (sorry data not formated) – madoro
