2.23 splot

`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` command.

See `plot` for features common to the `plot` command; only differences are discussed in detail here. Note specifically `plot`'s `axes` option is not available for `splot`.

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 ticslevel. The orientation of a `splot` projection is controlled by view. See view and 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, yrange, and zrange. In parametric mode, the order is urange, vrange, xrange, yrange, and zrange.

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

The datafile options have more differences.
