The QuantilePlot command generates a quantile-quantile plot for the specified data.

The first parameter X is the first data sample - given as a Vector or list.

The second parameter Y is the second data sample - given as a Vector or list.

The options argument can contain one or more of the options shown below. All unrecognized options will be passed to the plots[display] command. See plot[options] for details.

color=name, list, or range

This option specifies colors for the points and for the reference line. When a list of colors is given, the set of points and the reference line will be colored with the corresponding colors in the list. If a range of colors is given, the colors will be generated by selecting an appropriate number of equally-spaced points in the corresponding hue range.

method=integer[1..8]

Method for calculating the quantiles. See Statistics, Quantile for more details.

reference=truefalse

If reference is set to true, the reference line  will be drawn in the same plot. Default value is true.

samplesize=posint

The number of points to be plotted. The quantiles taken will be  for  The default value is 25.
