Displays density function contour.

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 2D 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 of the center of rectangles, forming a tessellation.

y

Y-axis coordinates of the center of rectangles, forming a tessellation.

z

Value at point (x, y).

alpha

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

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.

linetype

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

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 (on x and y direction correspondingly).

adjust

Adjusts 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.

colorBy

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

mapping

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