Fill and border colour in geom_point (scale_colour_manual) in ggplot
I'm doing an scatter plot using ggplot. I would like to have points with a particular colour and fill (in plot
, colour="blue", fill="cyan4"
, for ex.) but I can't find how. What I have to this point is:
ggplot(df, aes(own,method)) +
panel.configuration +
scale_shape_identity() + #to use the 'plot' shape format.
geom_point(aes(color = factor(label)), position = "jitter",size=3) +
(In previous geom_point
I tried adding shape=21
as I would have done in plot
)
scale_colour_manual(values=c("A"="chocolate3","B"="cyan4")) +
scale_fill_manual(values=c("A"="green", "B"="red")) + #DOES NOTHING...
xlim(7,47) + ylim(7,47)+ ... etc.
This is what i get without "shape=21"
This is what I get when I add "shape=21". In both cases it ignores scale_fill
I also tried adding fill=c("blue","red")
in geom_point, but R complains: "Error: Incompatible lengths for set aesthetics: shape, size, fill".
Any suggestions about how to get it? What is wrong with scale_fill
in my code?
Thank you very much!
Data (df) looks like:
21 15 A
24 16 A
24 17 A
28 14 A
24 15 A
22 15 A
20 18 A
24 18 A
34 9 B
38 12 B
41 19 B
42 13 B
36 12 B
40 17 B
41 14 B
37 12 B
40 13 B
37 15 B
35 15 B
Solution 1:
You'll have to use shapes from 21 to 25
. These are the ones that have colour
and fill
properties:
ggplot(df, aes(own, method)) +
geom_point(colour="white", shape=21, size = 4,
aes(fill = factor(label))) +
scale_fill_manual(values=c("blue", "cyan4"))
If you want different colours for colour
as well, then:
ggplot(df, aes(own, method)) +
geom_point(aes(colour=factor(label),
fill = factor(label)), shape=21, size = 4) +
scale_fill_manual(values=c("blue", "cyan4")) +
scale_colour_manual(values=c("white", "black"))
