Please read the posting guide and provide a (small) reproducible example
of your data.
The statement "...output does not seem good." is not very useful.
Please explain what you would like the polygon area to look like, and
why you don't like the way it came out. Links to posted images of the
chart would help too.

Hi everybody,
I have a matrix with 3 columns (Date, MeanArea and SdArea). I want to
draw a figure showing the variable MeanArea in terms of the Date. But
instead to use the variable SdArea as bar error, I want to use “polygon
error”. I use this code but the output does not seem good.
Poly<read.table("C:\\Users\\Momadou\\Documents\\AreaMonthly.csv",sep=";",dec=",",header=TRUE)
Poly
y <-MeanArea
x <-SdArea
z <-Date
matplot(x,cbind(y,z),type="n")
polygon(c(x,rev(x)),c(y,rev(z)),col="grey50")
Thank you in advance
