Perhaps just use a table, and skip the pie chart? --Chris Ryan On Mon, Aug 15, 2022 at 11:59 AM Ana Marija <sokovic.anamarija at gmail.com> wrote:> Hi All, > > I have df like this: > > > df# A tibble: 2 ? 4 > V1 n perc labels > <chr> <int> <dbl> <chr> 1 Yes 8 0.364 36% 2 No 14 0.636 64% > > I am making pie chart like this: > > library(ggplot2) > > ggplot(df, aes(x = "", y = perc, fill = V1)) + > geom_col(color = "black") + > geom_label(aes(label = labels), > position = position_stack(vjust = 0.5), > show.legend = FALSE) + > guides(fill = guide_legend(title = "Answer")) + > coord_polar(theta = "y") + > theme_void() > > How would I add in the legend beside Answer "Yes" count 8 (just number > 8) and beside "No" count 14? > > Thanks > > Ana > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >[[alternative HTML version deleted]]
V1=c("Yes","No")

perc=c(0.364,0.636)
labels=c("35%","64%")
df=data.frame(V1,n,perc,labels)
library(ggplot2)
ggplot(df, aes(x = "", y = perc, fill = V1)) +
geom_col(color = "black") +
geom_label(aes(label = labels),
position = position_stack(vjust = 0.5),
show.legend = FALSE) +
guides(fill = guide_legend(title = "Answer")) +
coord_polar(theta = "y") +

geom_text(aes(label=n), position=position_stack(vjust=0.25))
library(ggplot2)
ggplot(df, aes(x = "", y = perc, fill = V1)) +
geom_col(color = "black") +
geom_label(aes(label = labels),
position = position_stack(vjust = 0.5),

geom_text(aes(label=c("n=8","n=14")),

There are two variants of geom_text. They have slightly different output. Play
with vjust to get the location right.

Subject: [R] how to add count to pie chart legend
[External Email]
Hi All,
I have df like this:
> df# A tibble: 2 ? 4
V1 n perc labels
<chr> <int> <dbl> <chr> 1 Yes 8 0.364 36% 2 No
14 0.636 64%
I am making pie chart like this:
library(ggplot2)
ggplot(df, aes(x = "", y = perc, fill = V1)) +
geom_col(color = "black") +
geom_label(aes(label = labels),
position = position_stack(vjust = 0.5),
show.legend = FALSE) +
guides(fill = guide_legend(title = "Answer")) +
coord_polar(theta = "y") +
theme_void()
How would I add in the legend beside Answer "Yes" count 8 (just number
8) and beside "No" count 14?
Thanks
Ana

Hi Ana, A lot of work for a little pie. df<-read.table(text="V1 n Yes 8 No 14", header=TRUE, stringsAsFactors=FALSE) par(mar=c(5,4,4,4)) pie(df$n,df$V1,col=c(3,2),main="Yes and No", xlab="",ylab="",radius=1) legend(0.75,-0.8,paste(df$V1,df$n),fill=c(3,2), xpd=TRUE) Jim On Tue, Aug 16, 2022 at 1:59 AM Ana Marija <sokovic.anamarija at gmail.com> wrote:> > Hi All, > > I have df like this: > > > df# A tibble: 2 ? 4 > V1 n perc labels > <chr> <int> <dbl> <chr> 1 Yes 8 0.364 36% 2 No 14 0.636 64% > > I am making pie chart like this: > > library(ggplot2) > > ggplot(df, aes(x = "", y = perc, fill = V1)) + > geom_col(color = "black") + > geom_label(aes(label = labels), > position = position_stack(vjust = 0.5), > show.legend = FALSE) + > guides(fill = guide_legend(title = "Answer")) + > coord_polar(theta = "y") + > theme_void() > > How would I add in the legend beside Answer "Yes" count 8 (just number > 8) and beside "No" count 14? > > Thanks > > Ana > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.
