When splotting (even in view map mode) it is not possible to have x2ticks
Please execute the attached script
Thanks for the great work
Correct. It is not possible to use the x2 axis in splot.
This is an intrinsic limitation in the way that gnuplot stores data points.
However, there may be other ways to plot what you want.
For example, it may not be necessary to use splot + set view map;
the same plot may be achievable using the ordinary 2D plot command.
Perhaps you could explain what exactly you are trying to show?
