 `splot` is the command for drawing 3-d plots (well, actually projections on
 a 2-d surface, but you knew that).  It can create a plot from functions or
 a data file in a manner very similar to the `plot` (Note: plot ) command.

 See `plot` for features common to the `plot` command; only differences are
 discussed in detail here.  Note specifically that the `binary`
 (Note: binary ) and  `matrix` (Note: matrix ) options (discussed under
 "datafile-modifiers") are not available for `plot`.

 Syntax:
       splot {<ranges>}
             <function> | "<datafile>" {datafile-modifiers}}
             {<title-spec>} {with <style>}
             {, {definitions,} <function> ...}

 where either a <function> or the name of a data file enclosed in quotes is
 supplied.  The function can be a mathematical expression, or a triple of
 mathematical expressions in parametric mode.

 By default `splot` draws the xy plane completely below the plotted data.
 The offset between the lowest ztic and the xy plane can be changed by `set
 ticslevel`.  The orientation of a `splot` projection is controlled by
 `set view` (Note: view ).  See set view and nd `set ticslevel`
 (Note: ticslevel ) for more information.

 The syntax for setting ranges on the `splot` command is the same as for
 `plot`.  In non-parametric mode, the order in which ranges must be given is
 `xrange` (Note: xrange ),  `yrange` (Note: yrange ), and  `zrange`
 (Note: zrange ).  In parametric mode, the order is  `urange`
 (Note: urange ), `vrange` (Note: vrange ), xrange, yrange, and zrange.

 The `title` (Note: title ) option is the same as in plot.  The operation of
 of `with` (Note: with ) is also the same as in `plot`, except that the
 plotting styles available to `splot` are limited to `lines` (Note: lines ),
  `points` (Note: points ),  `linespoints` (Note: linespoints ),  `dots`
 (Note: dots ), and  `impulses` (Note: impulses );  the error-bar
 capabilities of `plot` are not available for `splot`.

 The datafile options have more differences.
