No - the attributes were fairly careful picked to actually be
distinguishable, which is very hard to do above a certain number of
colours/shapes/linetypes etc.
But your approach (creating your own scales) is basicall
15, 3, 7, 8)
} else {
c(1, 2, 0, 3, 7, 8, 1, 2, 0, 3, 7, 8, 1, 2, 0,
3, 7, 8)
})[1:length(.$domain())]
}
ScaleShape$max_levels <- function(.) 18

Hello,
the same parameter for colour and shape aesthetics gives 2 legends:
library(ggplot2)
p <- ggplot(mtcars, aes(x=wt, y=mpg))
p + geom_point(aes(colour=factor(cyl), shape=factor(cyl)))
Can the 2 legends be consolidated to one with
colours and shapes of the symbols matched between legend and
5 matches
