geomRaster

class geomRaster(val data: Map<*, *>? = null, val stat: StatOptions = Stat.identity, val position: PosOptions = positionIdentity, val showLegend: Boolean = true, val sampling: SamplingOptions? = null, val x: Number? = null, val y: Number? = null, val alpha: Number? = null, val fill: Any? = null, val fillBy: String? = null, mapping: RasterMapping.() -> Unit = {}) : Layer, RasterAesthetics, WithFillOption

Displays rectangles defined by the center of the tile (x, y). This is a high performance special function for same-sized tiles. Much faster than geomTile() but doesn't support width/height and color.

Examples

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

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

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.

y

Coordinates of the center of rectangles.

alpha

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

fill

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.

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".
