Add shading between series

Add shading between series

agg_shading(from, to, panel = NULL, colour = RBA["Grey2"], color)

Arguments

from	The series name to shade from (if you have no group aesthetic, it will be the name of the y variable); if you have groups, it will (usually) be the group identifier. This can get more complicated if you have duplicate group names. If so, arphit appends .y to the group names, so try that.)
to	The name of the series to shade to
panel	(optional) Which panel are the relevant series in? (arphit will try to find them if you don't specify)
colour	(optional) The colour to shade between the series (default grey)
color	(Deprecated; use colour instead) The colour to shade between the series (default grey)

Examples

data <- data.frame(date = seq.Date(from = as.Date("2000-03-10"), length.out = 12, by = "month"),
                   x1 = rnorm(12), x2 = rnorm(12))
arphitgg(data, agg_aes(x = date)) + agg_line(agg_aes(y = x1), colour = RBA["Blue2"]) +
   agg_line(agg_aes(y = x2), colour = RBA["Red4"]) +
   agg_shading(from = x1, to = x2)
