2.21.90 xyplane

The xyplane command adjusts the position at which the xy plane is drawn in a 3D plot. The synonym "set ticslevel" is accepted for backwards compatibility.

Syntax:

      set ticslevel <frac>
      set xyplane <frac>
      set xyplane at <zvalue>
      show xyplane

The form `set ticslevel <frac>` places the xy plane below the range in Z, where the distance from the xy plane to Zmin is given as a fraction of the total range in z. The default value is 0.5. Negative values are permitted, but tic labels on the three axes may overlap.

To place the xy-plane at a position 'pos' on the z-axis, ticslevel may be set equal to (pos - zmin) / (zmin - zmax). However, this position will change if the z range is changed.

The alternative form `set xyplane at <zvalue>` fixes the placement of the xy plane at a specific Z value regardless of the current z range. Thus to force the x, y, and z axes to meet at a common origin one would specify `set xyplane at 0`.
