## contourfill

Syntax:

         splot f(x,y) with contourfill {at base} {fillstyle <style>}

Contourfill is a 3D plotting style used to color a pm3d surface in slices along the z axis. It can be used in 2D projection (set view map) to create 2D contour plots with solid color between contour lines. The slice boundaries and the assigned colors are both controlled using set contourfill. See also pm3d, zclip.

This style can be combined with set contours to superimpose contour lines that bound the slices. Care must be taken that the slice boundaries from set contourfill match the contour boundaries from set cntrparam.

         # slice boundaries determined by ztics
         # coloring set by palette mapping the slice midpoint z value
         set pm3d border retrace
         set contourfill ztics
         set ztics -20, 5, 20
         set contour
         set cntrparam cubic levels increment -20, 5, 20
         set cntrlabel onecolor
         set view map
         splot g(x,y) with contourfill, g(x,y) with lines nosurface
