### New plot styles and style options

- 3D plot style with polygons reads polygon faces from a data file. This can be used to create a surface or to construct a solid object. See with polygons (p. ).
- splot $voxelgrid with {dotspoints} marks all voxels whose value is above a requested threshold level.
- splot $voxelgrid with isosurface creates a tessellated 3D surface enclosing voxels above a requested threshold level. See isosurface (p. ).
- Voxel grid values can be referenced in the using specifiers for 3D plots.
- set spiderplot selects a new plotting mode allowing creation of spider plots (also known as radar charts). These are essentially parallel axis plots where the axes are arranged radially rather than vertically. See spiderplot (p. ), set style spiderplot (p. ), set paxis (p. ).
- Plot style with circles can be used in 3D plots.
- Plot style with boxes can be used in 3D plots.
- 2D plot style with arrows is identical to with vectors except that each arrow is specified using x:y:length:angle rather than x:y:xdelta:ydelta
- splot FOO with pm3d fillcolor colorspec
- pm3d surfaces can have individual fillstyle and separate top/bottom fillcolor
- pm3d option noclipcb causes quadrangles with palette color outside cbrange to be skipped rather than being drawn with color clipped to cbmin or cbmax.
- Customized contour line types. See set cntrparam (p. ).
