(well... called Depayan)
The standard example
barchart(yield ~ variety | site, data = barley,
groups = year, layout = c(1,6), stack = TRUE,
auto.key = list(points = FALSE, rectangles = TRUE, space = "right"),
ylab = "Barley Yield (bushels/acre)",
scales = list(x = list(rot = 45)))
shows the problem: legend colors are inverted compared to stack colors.
This is still acceptable with 2 colors, but with 3 or more, people
ask me why it's partly down-under. I use to mumble that one
author is in New Zealand, the other either in India or in Wisconsin.
I know the hard way to correct this, but auto.key is nice because
it's print-time settings dynamic. Any easy workaround?
