Line layer

Connects observations in the order they appear, optionally split by a group or colour mapping.

Usage

orb_line(
  ...,
  data = NULL,
  width = 1.8,
  colour = NULL,
  alpha = 1,
  smooth = FALSE
)

Arguments

...

Aesthetic mappings for this layer only, as channel = column.

data

Optional data frame overriding the plot data.

width

Line width in pixels.

colour

Fixed colour used when the colour channel is not mapped.

alpha

Opacity between 0 and 1.

smooth

Draw a smoothed curve through the points instead of straight segments (a Catmull-Rom style spline). Default FALSE.

Value

An object of class orb_layer.

Examples

df <- data.frame(t = 1:50, v = cumsum(rnorm(50)))
orb(df, x = t, y = v) + orb_line(width = 2, smooth = TRUE)
#> <orb_spec>
#>   data:   50 rows x 2 columns
#>   mapping: x, y 
#>   layers:  line
