Displays a density estimate.

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.

geom

The geometry to display the density stat for this layer, default is density, see Geom.

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.html.

x

X-axis coordinates.

y

Y-axis coordinates.

alpha

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

color

Color of geometry lines. 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.

linetype

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

size

Lines width.

weight

Used by the stat to compute weighted density.

bw

The method (or exact value) of bandwidth. Can be String ("nrd0" or "nrd") or Double.

kernel

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

n

The number of sampled points for plotting the function.

trim

default = false If false, each density is computed on the full range of the data. If true, each density is computed over the range of that group.

adjust

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

fullScanMax

Maximum size of data to use density computation with 'full scan'. For bigger data, less accurate but more efficient density computation is applied.

quantiles

default = listOf(0.25, 0.5, 0.75). Calculates given quantiles of the density estimate.

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".
