+ ?plot data-file using
+ ?using
+  The format of data within a file can be selected with the `using`
+  option.  The `xy` and `yx` specify the order of the `x` and `y`
+  variables in the data file. To reverse the variables specify `yx`.
+  To specify that the datafile should contain one variable specify `y`.
+
+  Syntax:
+
+          plot "datafile" { using { xy | yx | y } {"scanf string"} } ...
+
+  If the `xy`, `yx` or `y` option is omitted, `xy` is used.
+  If the scanf string is omitted, the default of `"%f%f"` is used.
+
+  Examples:
+
+          plot "MyData" using yx "%*f%f%*20[^\n]%f" with lines
+  This causes data to be read from the file "MyData" using the format
+  `yx "%*f%f%*20[^\n]%f"`.  The meaning of this format is: `%*f`
+  ignore the first number, `%f` then read in the second and assign to y
+  (the `yx` option of using), `%*20[^\n]` then ignore 20 non-newline
+  characters, `%f` then read in the x value.
+
+          plot "MyData" using "%f%f", "MyData" using "%f%*f%f"
+  Causes gnuplot to plot the second and third columns of MyData versus
+  the first column.
+
+  Note: gnuplot first reads a line of the data file into a buffer and
+  then does a
+          sscanf(input_buffer, scanf_string, &x, &y);
+  where `x` and `y` are of type `float`.  Any scanf string that specifies
+  two `float` numbers may be used.

+ ?plot parametric
+ ?parametric
+  When in parametric mode (`set parametric`) mathematical expressions must
+  be given in pairs:
+   plot sin(t),t**2
+
+  Data files are plotted as before, except the parametric function
+  must be fully specified before a data file is given as a plot.  In
+  other words, the x parametric function (sin(t) above) and the y
+  parametric function (t**2 above) must not be interrupted with any
+  modifiers or data functions; doing so will generate a syntax error
+  stating that the parametric function is not fully specified.
+
+  Ranges take on a different meaning when in parametric mode.  The
+  first specifiable range on the plot command is the trange, the
+  next the xrange, and the last is the yrange.  The following plot
+  shows setting the trange to [-pi:pi], the xrange to [-1.3:1.3]
+  and the yrange to [-1:1] for the duration of the plot:
+   plot [-pi:pi] [-1.3:1.3] [-1:1] sin(t),t**2
+
+  Other modifiers, such as `with` and `title` are required after
+  the function has been fully specified:

+ ?autoscale parametric
+ ?set autoscale t
+  When in parametric mode (`set parametric`) the xrange is as
+  fully scalable as the yrange.  In other words, in parametric
+  mode the X axis can be automatically scaled to fit the range
+  of the parametric function that is being plotted.  Of course,
+  the Y axis can also be automatically scaled just as in the
+  non-parametric case.  If autoscaling on the X axis is not set,
+  the current X range is used.
+
+  When there is a mix of data files and functions, the xrange of
+  the functions is selected as that of the data files if autoscale
+  is true for X.  While this keeps the behavior compatible with
+  non-parametric plotting, it may not be retained in the future.
+  The problem is that, in parametric mode, the x and y ranges are
+  not as distinguishable as in the non-parametric mode and this
+  behavior may not be the most useful.
+
+  For completeness sake a last command `set autoscale t` is accepted.
+  However, the effect of this "scaling" is very minor.  When
+  gnuplot determines that the t range would be empty it makes a
+  small adjustment if autoscaling is true.  Otherwise, gnuplot
+  gives an error.  Such behavior may, in fact, not be very useful
+  and the command `set autoscale t` is certainly questionable.

+ 3 parametric
+ ?set parametric
+ ?show parametric
+ ?parametric
+  The `set parametric` command changes the meaning of the plot from
+  normal functions to parametric functions.  The command
+  `set noparametric` changes the plotting style back to normal,
+  single-valued expression plotting.
+
+  Parametric functions are determined by a pair of functions
+  operating on a `parameter`, such as sin(t),cos(t) (which describes
+  a circle if `t` ranges over [-pi:pi]).  Hence it takes two
+  parametric function specifications in terms of the parametric
+  dummy argument to describe a single graph.
+
+  The total set of possible plots is a superset of the simple f(x)
+  style plots, since the two functions can describe both the
+  x and y values to be computed separately.  In fact, plots of
+  the type t,f(t) are equivalent to those produced with f(x) since
+  the x values are computed with just the identity function.  Note
+  that the order the parametric function is specified is xfunction,
+  yfunction and that each operates over the common parametric domain.
+
+  Also, the `set parametric` function implies a new range of values.
+  Whereas the normal f(x) style plotting assumes an xrange and yrange,
+  the parametric mode additionally specifies a trange.  The trange
+  may be specified directly with `set trange`, by specifying the
+  range on the plot command, or indirectly with `set autoscale t`.
