geom_dash: Dashes

In Clement-Viguier/ggvis:

Description

'geom_dash' draws a dash around points (x, y). Couyld be useful for custom data visualisation, or distribution or vector fields. For those scenarios it's more convenient than geom-segment.

Usage

geom_dash(mapping = NULL, data = NULL, stat = "identity",
  position = "identity", ..., arrow = NULL, arrow.fill = NULL,
  lineend = "butt", linejoin = "round", relative = F,
  na.rm = FALSE, show.legend = NA, inherit.aes = TRUE)

Arguments

mapping	Set of aesthetic mappings created by aes() or aes_(). If specified and inherit.aes = TRUE (the default), it is combined with the default mapping at the top level of the plot. You must supply mapping if there is no plot mapping. The 'geom_dash' is characterised by specific aes() that encore different dimensions: 'width': the length of the dash, 'angle': the angle of the dash and 'start' [0-1]the relative position of the starting point of the dash (0.5 by default).
arrow	specification for arrow heads, as created by arrow().
arrow.fill	fill colour to use for the arrow head (if closed). 'NULL' means use 'colour' aesthetic.
lineend	Line end style (round, butt, square).
linejoin	Line join style (round, mitre, bevel).
relative	if TRUE normalize the dash width relative to the maximum value of width to avoid overlapping (default = F).

Examples

iris %>% ggplot(aes(Species , Petal.Length)) + geom_dash(width = 0.8)
