geomMap

class geomMap(val data: Map<*, *>? = null, val stat: StatOptions = Stat.identity, val position: PosOptions = positionIdentity, val showLegend: Boolean = true, val sampling: SamplingOptions? = null, val tooltips: TooltipOptions? = null, val map: SpatialDataset? = null, val mapJoin: <Error class: unknown class><Any, Any>? = null, val useCRS: String? = null, val x: Number? = null, val y: Number? = null, val size: Number? = null, val linetype: Any? = null, val color: Any? = null, val fill: Any? = null, val alpha: Number? = null, val colorBy: String? = null, val fillBy: String? = null, mapping: PolygonMapping.() -> Unit = {}) : Layer, PolygonAesthetics, WithSpatialParameters, WithColorOption, WithFillOption

Displays a filled closed path defined by the vertex coordinates of individual polygons. geomMap is essentially the same as geomPolygon but uses 'coordMap' as default coordinate system.

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.

map

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

Supported shapes: Polygon and MultiPolygon. 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 coordinates of the vertices of the polygon.

y

Y-axis coordinates of the vertices of the polygon.

alpha

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

color

Color of geometry lines. 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.

size

Line width.

linetype

Type of the line. Codes and names: 0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash", 5 = "longdash", 6 = "twodash".

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.

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".
