geomContour

class geomContour(val data: Map<*, *>? = null, val stat: StatOptions = Stat.contour(), val position: PosOptions = positionIdentity, val showLegend: Boolean = true, val inheritAes: Boolean? = null, val manualKey: Any? = null, val sampling: SamplingOptions? = null, val tooltips: TooltipOptions? = null, val x: Number? = null, val y: Number? = null, val z: Number? = null, val alpha: Number? = null, val color: Any? = null, val linetype: Any? = null, val size: Number? = null, val bins: Int? = null, val binWidth: Number? = null, val colorBy: String? = null, mapping: ContourMapping.() -> Unit = {}) : Layer, PathAesthetics, ContourStatAesthetics, ContourStatParameters, WithColorOption

Displays contours of a 3d surface in 2d.

Notes

Computed variables:

..level.. : height of a contour.

To hide axis tooltips, set "blank" or the result of elementBlank() to the axisTooltip, axisTooltipX or axisTooltipY parameter of the theme().

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.contour(). 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.

inheritAes

default = true. false - do not combine the layer aesthetic mappings with the plot shared mappings.

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. Set tooltips = tooltipsNone to hide tooltips from the layer.

bins

Number of levels.

binWidth

Distance between levels.

X-axis coordinates of the center of rectangles, forming a tessellation.

Y-axis coordinates of the center of rectangles, forming a tessellation.

Value at point (x, y).

alpha

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

color

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

linetype

Type of the line. Accept codes or names (0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash", 5 = "longdash", 6 = "twodash"), a hex string (up to 8 digits for dash-gap lengths), or a pattern offset to listOf(dash, gap, ...) / listOf(dash, gap, ...). For more info see: aesthetics.html#line-types.

size

Line width.

colorBy

default = "color" ("fill", "color", "paint_a", "paint_b", "paint_c"). Defines the color aesthetic for the geometry.

mapping

Set of aesthetic mappings. Aesthetic mappings describe the way that variables in the data are mapped to plot "aesthetics".
