Draws points defined by an x and y coordinate.

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.

tooltips

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

orientation

Specifies the axis that the layer's stat and geom should run along, default = "x". Possible values: "x", "y".

map

Data-structure containing series of planar shapes and, optionally, associates data series (for example: names of States and their boundaries).

Supported shapes: Point and MultiPoint. All coordinates should be encoded as decimal degrees in WGS84 coordinate reference system.

Can be used with parameter mapJoin for joining data and map coordinates.

mapJoin

Pair of Names or Pair of Lists of Names. Specifies column names to join the data and the map coordinates on.

  • Pair.first: column name or list of column names in the data dataframe.

  • Pair.second: column name or list of column names in the map dataframe.

useCRS

By default, all coordinates are converted into degrees of longitude and latitude, and these map coordinates are projected onto the screen coordinates using Mercator projection. Specify useCRS = "provided" to keep the SpatialDataset's original coordinate reference system (CRS).

x

X-axis value.

y

Y-axis value.

alpha

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

color

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 to paint shape's inner points. Is applied only to the points of shapes having inner points. 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.

shape

Shape of the point.

size

Size of the point.

stroke

Width of the shape border. Applied only to the shapes having border.

angle

Rotation angle of the shape, in degrees.

sizeUnit

Relates the size of the point to the length of the unit step along one of the axes. Possible values: "x", "y". If not specified, no fitting is performed.

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".
