Hi,
I'm trying to plot stacked barplot with lines on it. Here is the data.
emp days val1 val2 score
1 21 1 0 1200
2 35 1 1 na
3 42 na na 3000
4 53 2 1 2100
5 64 1 0 na
6 73 na na 1400
My X-axis is days. I'm looking to plot val1,val2 as stacked bars and score
as lines with different y-axis. I could get the bar plot and lines on it
but the problem is the bars and lines are not aligning well for same point
on X-axis. Note, that there might not be a score for some when there is
val1 and val2 or vice versa. Any help in this regard is highly appreciated.
Hi SK,
Your alignment problem is due to the way barplot spaces the bars. Try this:
mydata<-read.table(textConnection(
"emp days val1 val2 score
1 21 1 0 1200
2 35 1 1 na
3 42 na na 3000
4 53 2 1 2100
5 64 1 0 na
6 73 na na 1400"),
header=TRUE,na.strings="na")
barpos<-barplot(as.matrix(mydata[c(1,2,4,5),c("val1","val2")]))
Then use "barpos" as the x locations of your values for the lines.
Jim
