Your excel plot did not come along with your message, so I'm not
quite sure what you're looking for. I won't let that stop me
from suggesting something though!
I know you've said lattice is not working for you, but I still
recommend it - something like
df <- read.table('tmp.dat',header=T)
Other wise you can use dotchart, which is in the base library.
Try something like this:
dotchart(tapply(df$DATA, list(df$SITE,paste(df$GRINDER,df$EQUIPID)), mean))
