Parameters

data

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.

stat

default = Stat.density2DFilled(). The statistical transformation to use on the data for this layer. Supported transformations: Stat.identity, Stat.bin(), Stat.count(), etc. see Stat.

position

Position adjustment: positionIdentity, positionStack(), positionDodge(), etc. see Position.

showLegend

default = true. false - do not show legend for this layer.

sampling

Result of the call to the samplingXxx() function. To prevent any sampling for this layer pass value samplingNone. For more info see sampling.md.

tooltips

Result of the call to the layerTooltips() function. Specifies appearance, style and content.

kernel

The kernel used to calculate the density function. Choose among "gaussian", "cosine", "optcosine", "rectangular" (or "uniform"), "triangular", "biweight" (or "quartic"), "epanechikov" (or "parabolic").

The method (or exact value) of bandwidth. Either a String (choose among "nrd0" and "nrd"), or a Double array of length 2.

weight

Used by density stat to compute weighted density.

The number of sampled points for plotting the function (on x and y direction correspondingly).

adjust

Adjust the value of bandwidth by multiplying it. Changes how smooth the frequency curve is.

contour

If true, contour the results of the 2d density estimation.

bins

Number of levels.

binWidth

Distance between levels.

X-axis coordinates.

Y-axis coordinates.

alpha

Transparency level of a layer. Understands numbers between 0 and 1.

size

Line width.

linetype

Type of the line. Codes and names: 0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash", 5 = "longdash", 6 = "twodash".

color

Color of geometry. String in the following formats:

RGB/RGBA (e.g. "rgb(0, 0, 255)")
HEX (e.g. "#0000FF")
color name (e.g. "red")
role name ("pen", "paper" or "brush")

Or an instance of the java.awt.Color class.

fill

Fill color. String in the following formats:

RGB/RGBA (e.g. "rgb(0, 0, 255)")
HEX (e.g. "#0000FF")
color name (e.g. "red")
role name ("pen", "paper" or "brush")

Or an instance of the java.awt.Color class.

colorBy

default = "color" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the color aesthetic for the geometry.

fillBy

default = "fill" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the fill aesthetic for the geometry.

mapping

Set of aesthetic mappings. Aesthetic mappings describe the way that variables in the data are mapped to plot "aesthetics".
