Rotation angles are defined with angle = 0 along the x axis, with increasing positive rotation angle corresponding to counterclockwise rotation about the start of the label.
So "rotate by 90" does indeed rotate the axis labels up into the plot. This is true in general and is independent of the output device (terminal). If you want the tics to go down instead, you need to request "rotate by 270" or equivalently "rotate by -90" FYI: Old versions of the program (before there was any support for providing arbitrary rotation angles) placed the labels differently. If you say "set xtics rotate" with no angle specified at all, the program emulates the old behaviour. This may depend on whether the executable was built with ./configure --enable-backwards-compatibility -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
