geom Bar
Displays a bar chart which makes the height of the bar proportional to the number of observed variable values, mapped to x-axis.
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.count()
. The statistical transformation to use on the data for this layer. Supported transformations: Stat.identity
, Stat.bin()
, Stat.count()
, etc. see Stat.
default = positionStack()
. 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.
Result of the call to the layerLabels()
function. Specifies style and content of the annotations.
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-axis value (this value will produce cases or bins for bars).
Y-axis value (this value will be used to multiply the case's or bin's counts).
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.
Width of a bar.
Defines bar line width.
Used by Stat.count()
stat to compute weighted sum instead of simple count.
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".
