ZValue Keyword

Used With Routines:   AXIS,  BAR3D, CONTOUR,  CONTOURFS,  CONTOUR,  OPLOT,  PLOT,  SHADE_SURF,   SURFACE

Corresponding System Variable: None.

Sets the z-coordinate, in normalized coordinates in the range of 0 to 1, of the axis and data output from PLOT, OPLOT, CONTOUR, and CONTOUR2.

This has an effect only if !P.T3d is set and the three-dimensional to two-dimensional transformation is stored in !P.T. If ZValue is not specified, CONTOUR and CONTOUR2 will output each contour at its z-coordinate, and the axes and title at a z-coordinate of 0.0.
