Hello,
Glad it helped.
As for making everything red, that only happens with the 2nd geom_text I
posted. And this is because color = "red" is not in aes().
In the 1st geom_text, I have aes( etc , color = gender)
and this makes the color depend on gender.
To make the text and bars colors the same, put color = gender in the
initial call to ggplot. Like this, all geom_ (layers) will inherit that
aesthetic.
And you don't need group = gender, fill or color already group the data.
ggplot(aes(x=year, y=percentage, fill=gender, color=gender), data =
graph_text)+
rest_of_code
Hope this helps,
Rui Barradas

Thank you very much for the elaborate response, Dr. Barradas! It was
extremely helpful!
This resolves all my queries except one; I am unable to assign aesthetic
colors in a way that the bar and text colors remain the same. I am not
sure how to exactly assign color outside of aes. I used the following
code which made everything red (and I want only text on top of the red
bars to be red, rest to be blue according to their bar colors)
ggplot(aes(x=year, y=percentage, group=gender, fill=gender), data =
graph_text)+
geom_bar(position = 'dodge', stat='identity')+
theme_classic()+
geom_text(aes(label = percentage), size = 5, position =
position_dodge(width = 0.9), vjust=0, color = "Red") +
scale_y_continuous(limits=c(0, 1.1*ymax))
Thank you very much for your time and help, Dr. Barradas!

Hello,
First, sample data.
set.seed(2021)
year <- rep(2016:2019, 2)
percentage <- runif(length(year), 0.25, 0.70)
gender <- rep(c("M", "F"), each = 4)
graph_text <- data.frame(year, percentage, gender)
1) You have expand = c(0,0). Like this there is no space above the
greatest bar. In order to make room, change to limits = c(0, ymax + 10
percent).
2) Make the width of the bars larger, position_dodge(width = 0.9)
3) Assign a aesthetic color in geom_text, if you want the bars and text
colors to be the same, assign a value outside aes() if you want only one
color for the text. See at the end.
4) Not asked but I use scales::percent to make the percentages
automatic. Change back to your code if not needed.
ymax <- max(graph_text$percentage)
ggplot(aes(x=year, y=percentage, group=gender, fill=gender), data =
graph_text)+
geom_bar(position = 'dodge', stat='identity')+
geom_text(
aes(label = scales::percent(percentage, accuracy = 0.1), color =
gender),
position = position_dodge(width = 0.9),
size = 5,
vjust = 0
)+
scale_y_continuous(
limits = c(0, 1.1*ymax),
labels = scales::percent
)+
theme_classic()
The following geom_text will change the text labels color to red.
geom_text(
aes(label = scales::percent(percentage, accuracy = 0.1)),
position = position_dodge(width = 0.9),
#
color = "red",
#
size = 5,
vjust = 0
)
Hope this helps,
