geom
A violin plot is a mirrored density plot with an additional grouping as for a boxplot.
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.yDensity(). The statistical transformation to use on the data for this layer. Supported transformations: Stat.identity, Stat.bin(), Stat.count(), etc. see Stat.
default = positionDodge(). 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.
Specifies the axis that the layer's stat and geom should run along. The default value (null) automatically determines the orientation based on the aesthetic mapping. If the automatic detection doesn't work, it can be set explicitly by specifying the "x" or "y" orientation.
Draw horizontal lines at the given quantiles of the density estimate.
default = false. Show the quantile lines.
default = 0.
If -1 then it's drawing only half of each violin.
If 1 then it's drawing other half.
If 0 then violins looking as usual.
X-axis coordinates.
Y-axis coordinates.
Density scaled for the violin plot, according to area, counts or to a constant maximum width.
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".
Lines width. Defines line width.
Width of violin bounding box.
Used by Stat.yDensity() stat to compute weighted density.
default = "area".
If "area", all violins have the same area.
If "count", areas are scaled proportionally to the number of observations.
If "width", all violins have the same maximum width.
default = 3.0. Extends domain of each violin on tailsCutoff * bw if trim = false.
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 = true. Trims the tails of the violins 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".
