qq Plot
Produces a Q-Q plot (quantile-quantile plot).
Supply the sample
parameter to compare distribution of observations with a theoretical distribution ('normal' or as otherwise specified by the distribution
parameter). Alternatively, supply x
and y
parameters to compare the distribution of x
with the distribution of y
.
Examples
Parameters
The data to be displayed in this layer. If null, the default, the data is inherited from the plot data as specified in the call to letsPlot.
Name of variable. Specifies a vector of observations used for computing of "sample quantiles". Use this parameter to produce a "sample vs. theoretical" Q-Q plot.
Name of variable specifying a vector of observations used for computing of x "sample quantiles". Use x
and y
parameters to produce a "sample X vs. sample Y" Q-Q plot.
Name of variable specifying a vector of observations used for computing of y "sample quantiles". Use x
and y
parameters to produce a "sample X vs. sample Y" Q-Q plot.
default = "norm". Distribution function to use: "norm", "uniform", "t", "gamma", "exp", "chi2". Could be specified if sample
is.
Additional parameters passed on to distribution function. Could be specified if sample
is.
If
distribution
is "norm" thendParams
is a pair (mean, std) (default = listOf(0.0, 1.0)).If
distribution
is "uniform" thendParams
is a pair (a, b) (default = listOf(0.0, 1.0)).If
distribution
is "t" thendParams
is an integer number (d) (default = listOf(1)).If
distribution
is "gamma" thendParams
is a pair (alpha, beta) (default = listOf(1.0, 1.0)).If
distribution
is "exp" thendParams
is a float number (lambda) (default = listOf(1.0)).If
distribution
is "chi2" thendParams
is an integer number (k) (default = listOf(1)).
default = Pair(0.25, 0.75). Pair of quantiles to use when fitting the Q-Q line.
Grouping parameter. If it is specified and color-parameters isn't then different groups will have different colors.
default = true. false - do not show legend for this layer.
Color of a points. For more info see: aesthetics.html#color-and-fill.
Color to paint shape's inner points. Is applied only to the points of shapes having inner points.
default = 0.5. Transparency level of a points. Understands numbers between 0 and 1.
default = 3.0. Size of the points.
Shape of the points. For more info see: aesthetics.html#point-shapes.
default = "#FF0000". Color of the fitting line.
default = 0.75. Width of the fitting line.
Int or String. Type of the fitting line. Codes and names: 0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash", 5 = "longdash", 6 = "twodash". For more info see: aesthetics.html#line-types.
