Betreff: Re: [R] ColorBrewer question
I believe you need to use the scale_fill_brewer since fill is the
color of the bars while color is the outside of the bars in
ggplot2-speak:
E.g., with built-in data (it's polite to provide yours so that your
minimal working example is working):
data(diamonds)
ggplot(diamonds, aes(clarity)) + geom_bar(aes(fill = clarity, color = clarity))
# Note the borders are now changed but the fill is the same
ggplot(diamonds, aes(clarity)) + geom_bar(aes(fill = clarity, color =
clarity)) + scale_color_brewer(pal = Blues)
# Now the fill is changed, but you probably want to drop the border
coloring since it's hideous against the blues
ggplot(diamonds, aes(clarity)) + geom_bar(aes(fill = clarity, color =
clarity)) + scale_fill_brewer(pal = Blues)
# So lovely
ggplot(diamonds, aes(clarity)) + geom_bar(aes(fill = clarity)) +
scale_fill_brewer(pal = Blues)

Hello, R friends,
I'm trying to change colors of my horizontal bars so that they show a
sequence.
I chose the ColorBrewer palette Blues. However the resulting plot doesn't
show any changes to the default.
I tried several places of + scale_colour_brewer(type=seq, pal = Blues)
with no effect.
This is my code:
p - ggplot(data, aes(x = gender)) +
scale_y_continuous(,formatter=percent) + xlab(Gender) + coord_flip() +
scale_colour_brewer(type=seq, pal = Blues)
p+geom_bar(aes(fill=pet),colour='black',position='fill')
Any ideas welcome.
Thanks,
Mario
