Hi Christophe,
Although I'm a fan of ggplot2, it's lack of documentation is a drawback.
I was having a similar problem and Hadley suggested the "sc$legend <-
FALSE" solution. AFAIK it isn't documented (yet). Have a look at
Hadley's website and the archive of this list for more documentation.
This code adds a solid border to to bars. But I can't figure out how to
add the main title to the plot (using ggplot instead of qplot).
library(ggplot2)
dow <- data.frame(dayofweek = factor(1:7), p = runif(7), w = c(0, 1, 1,
1, 1, 1, 0))
sc <- scale_fill_continuous()
sc$legend <- FALSE
ggplot(data = dow, aes(x = dayofweek, y = p, fill = w), "t") +
scale_x_discrete("Day") + scale_y_continuous("Arrival Rate") +
geom_bar(colour = "black") + sc
Cheers,
Thierry
