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.
