Hi,
you can use par.settings to get a consistent color scheme,
pal1 <- rgb(196, 255, 255, max = 255)
pal2 <- rgb( 0, 35, 196, max = 255)
df <- data.frame( Gruppe = c("A", "B", "A", "B"),
Kat = c("x1", "x1", "w1", "w1"),
value= c(1,2, 4, 5))
barchart(value ~ Kat, group= Gruppe,
par.settings = list(superpose.polygon = list(col=c(pal1, pal2)) ),
panel = function(y,x,...){
panel.barchart(x,y, ...)
}, data = df,
auto.key = list(points = FALSE, rectangles = TRUE,
columns = 2, space = "bottom")
)
HTH,

Dear list,
with the code below I produce the right graph, but the colours of
the legend are different from the colours of the graph. The colours
of the graph are the desired colours.
Thanks for any help.
