geom
Plots the sum of the y and height aesthetics versus x. Heights of the ridges are relatively scaled.
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.
default = Stat.densityRidges(). The statistical transformation to use on the data for this layer. Supported transformations: Stat.identity, Stat.bin(), Stat.count(), etc. see Stat.
Position adjustment: positionIdentity, positionStack(), positionDodge(), etc. see Position.
default = true. false - do not show legend for this layer.
Result of the call to the samplingXxx() function. To prevent any sampling for this layer pass value samplingNone. For more info see sampling.md.
Result of the call to the layerTooltips() function. Specifies appearance, style and content.
X-axis coordinates.
Y-axis coordinates.
Height of the ridge. Assumed to be between 0 and 1, though this is not required.
Quantile values to draw quantile lines and fill quantiles of the geometry by color.
Transparency level of a layer. Understands numbers between 0 and 1.
Color of the 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 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.
Type of the line of border. Codes and names: 0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash", 5 = "longdash", 6 = "twodash".
Defines line width.
Used by Stat.densityRidges() stat to compute weighted density.
default = 1.0 A multiplicative factor applied to height aesthetic. If scale = 1.0, the heights of a ridges are automatically scaled such that the ridge with height = 1.0 just touches the one above.
default = 0.0. A height cutoff on the drawn ridges. All values that fall below this cutoff will be removed.
default = false. Shows the quantile lines.
Extends domain of each ridge on tailsCutoff * bw if trim = false. tailsCutoff = null (default) extends domain to maximum (domain overall ridges).
default = listOf(0.25, 0.5, 0.75). Draws horizontal lines at the given quantiles of the density estimate.
String or Double. The method (or exact value) of bandwidth. Either a string (choose among "nrd0" and "nrd") or a double.
The kernel we use to calculate the density function. Choose among "gaussian", "cosine", "optcosine", "rectangular" (or "uniform"), "triangular", "biweight" (or "quartic"), "epanechikov" (or "parabolic").
The number of sampled points for plotting the function.
default = false. Trims the tails of the ridges to the range of the data.
Adjusts the value of bandwidth by multiplying it. Changes how smooth the frequency curve is.
Maximum size of data to use density computation with "full scan". For bigger data, less accurate but more efficient density computation is applied.
default = "color" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the color aesthetic for the geometry.
default = "fill" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the fill aesthetic for the geometry.
Set of aesthetic mappings. Aesthetic mappings describe the way that variables in the data are mapped to plot "aesthetics".
