Hi Huapeng, Firstly, it is worth noting that it is often not recommended to overlay series with different scales, so you should think about other ways to present your data.
Secondly, when posting here it is much more helpful to provide the data in a form that can be copied-and-pasted into R: so rather than print(mydata), please use dput(mydata). Regarding the doubleYScale() function from the latticeExtra package, since you are overlaying grouped plots you should give use.style = FALSE. Then specify an appropriate par.settings list to the final plot, which might be par.settings = simpleTheme(fill = c("dark gray", "light gray", "white"), col = "black", pch=c(16,17), lty=c(1,2)) I haven't tested this, but I can if you send me your data in a dput() form. Regarding a composite key, you could construct it using the general 'key' argument described in ?xyplot or if you want two keys in different positions that would also be possible. The doubleYScale() function was not really designed for handling such complex plots... and again, I would encourage you to think about simpler ways to present your data. Hope that helps -Felix On 4 June 2010 01:48, Chen, Huapeng FOR:EX <huapeng.c...@gov.bc.ca> wrote: > > Hello, > > I am new to R.
