# I am constructing a bar chart using ggplot, as in the example below.
# I want to highlight "Series 2" by colouring the bar red,
# with the other bars coloured blue. That works.
# I also want to colour the label "Series 2" (only) in red, but I have 
# been able to find a way to do that.
# Here is the example:

# Test data
dta <- data.frame(dta_names=c("Series 1","Series 2","Series 3","Series 
dta$dta_names <- as.character(dta$dta_names) # convert from factor
# Bar chart
ggplot(dta,aes(x=dta_names,y=dta_values)) +
   geom_bar(stat="identity",fill="darkblue") +
   geom_bar(data=dta[2, ],stat="identity",aes(x=dta_names, y=dta_values), 
fill="red") +
   labs(title = "Example bar chart") +

# Any suggestions appreciated.
