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

position

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

showLegend

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

manualKey

String or result of the call to the layerKey() function. The key to show in the manual legend. Specifies the text for the legend label or advanced settings using the layerKey() function.

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.

tooltips

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

labels

Result of the call to the layerLabels() function. Specifies style and content of the annotations.

orientation

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.

x

X-axis value (this value will produce cases or bins for bars).

y

Y-axis value (this value will be used to multiply the case's or bin's counts).

alpha

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

color

Color of the geometry. For more info see: aesthetics.html#color-and-fill.

fill

Fill color. For more info see: aesthetics.html#color-and-fill.

width

Width of a bar.

size

Defines bar line width.

weight

Used by Stat.count() stat to compute weighted sum instead of simple count.

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".
