Hi Ethan, It worked ! Thank you so much !! Regards, Marc

Hi, I can't understand why the following lines (in gnuplot 5.0, under fedora) : set samples 1000 f(x) = ( 1e-1 + 1/100 - sqrt( (1e-1 + 1/100)2 - 4x(1-x)*1e-2 ) )/2 set xrange [0:1] plot f(x) w l ls 3 lw 2 title 'f' lead to a linear plot when it should be curved (these same lines work perfectly fine with scilab, for instance). I've been trying to solve that for a couple of days now, without success... when f(x) = x(1-x) or f(x) = sqrt(x(1-x)) it works fine: no linear segment but curved stuff as expected......

Do I do something wrong...
