Time series graph

[serdar neslihanoglu]

Can you help me to create time series graph (acf and pacf ) wıth
ggplot2 ?
Do you have an example related to this subject ?

[Mike Lawrence]

There are plenty of time series plots demonstrated in the ggplot2 book
(http://had.co.nz/ggplot2/book/). If you need further help, please ask
a more detailed question and provide small reproducible examples.

ok
I have already checked the ggplot book but
thıs book only has tıme serıes lıne graph.
Moreover , ggplot book never show how to
draw ACF and Pacf graph of tıme serıes.
Do you have another ıdea of tıme serıes graph?

Hi Serdar (and ggplot people at large, just joined the list...)

I don't think ggplot has anything to calculate ACF/PACF but that's ok,
you can calculate the values with R and plot them with ggplot:

#lh is an example dataset which is a time series
#?acf should let you decide how to handle your data

d <- acf(lh, plot=FALSE)
df <- data.frame(d$lag, d$acf)
p <- ggplot(df, aes(d.lag, d.acf))
p + geom_bar(stat='identity')

I don't know how to make the bars as skinny as ACF plots usually are,
I tought geom_bar(width=....) would do the trick but it doesn't appear
to...

Hope that helps,
David

just adding a reply from JiHO that went to me rather than me group so
future google-ers can get the answer :)

For some reason, widths needs to be in a aes call currently.

p + geom_bar(stat='identity', aes(width=0.2))
