Draws a curved line.

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.

curvature

default=0.5. The amount of curvature. Negative values produce left-hand curves, positive values produce right-hand curves,

angle

default=90. Angle in degrees, giving an amount to skew the control points of the curve. Values less than 90 skew the curve towards the start point and values greater than 90 skew the curve towards the end point.

ncp

default = 5. The number of control points used to draw the curve. More control points creates a smoother curve.

spacer

default = 0.0. Space to shorten a curve by moving the start/end.

arrow

Specification for arrow head, as created by arrow() function.

x

X-axis value.

y

Y-axis value.

xend

X-axis value.

yend

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.

linetype

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

size

Line width.

sizeStart

Offset from the start coordinate. Usually equal to the size of the point object from which the curve starts to avoid overlapping with it.

sizeEnd

Offset from the end coordinate. Usually equal to the size of the point object from which the curve ends to avoid overlapping with it.

strokeStart

Offset from the start coordinate. Usually equal to the stroke of the point object from which the curve starts to avoid overlapping with it.

strokeEnd

Offset from the end coordinate. Usually equal to the stroke of the point object from which the curve ends to avoid overlapping with it.

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".
