I am struggling though to understand why a 'two co-ordinate' plot I have returns an error 'all points y2 value undefined!' My plot is (I think) is quite simple. --snip-- set xtics nomirror set ytics nomirror set y2tics plot "-" u 1:2 t "Foo" axes x1y1 with boxes, "" u 1:3 t "Bar" axes x1y2 w lines 1996 21 1 1997 161 2 1998 138 5 1999 225 6 2000 344 9 2001 276 5 2002 991 7 2003 995 7 --snip-- And I cannot work out what the error is referring to. Isn't 'y2' implied by the third column? Thank you for any help. Regards James
