Why The Origin Of Z-axis Is Not On The Xy-plane?

1.	Why The Origin Of Z-axis Is Not On The Xy-plane?
Answer» The zero-point of Z-axis is placed above the XY plane of splot. ‘set ticslevel’ is used to move this ORIGIN onto the XY plane. By SETTING ticslevel=0, the zero of Z-axis moves onto the XY plane. The following is the SCRIPT to do this: gnuplot> set ticslevel 0 gnuplot> splot (X*2)(y**2)

Answer»

The zero-point of Z-axis is placed above the XY plane of splot.
‘set ticslevel’ is used to move this ORIGIN onto the XY plane.
By SETTING ticslevel=0, the zero of Z-axis moves onto the XY plane.
The following is the SCRIPT to do this:
gnuplot> set ticslevel 0
gnuplot> splot (X**2)*(y**2)
