dotplot: labeling coordinates for each point

Hi Deepayan, I guess I?m quite confusing when asking the question. I was actually looking for labels beside the dot in the graph (shown below), rather than the labels on the x-axis. Is that possible? Thanks a lot!
In that case
dotplot(y ~ x, xlab="Store", ylab="Revenue", main="test",
scales=list(x = list(draw = FALSE)),
panel = function(x, y, ...) {
panel.dotplot(x, y, ...)
id <- y > 90
panel.text(as.numeric(x[id]), y[id],
labels = sprintf("(%s,%g)", as.character(x[id]), y[id]),
pos = 4)
})

Hi Deepayan,
Thanks for the reply. here is a very simple example of what I'm looking for:
y=c(100,0,-20)
x=c("Atlanta", "Baltimore", "Berkeley CA")
dotplot(y~x, xlab="Store", ylab="Revenue",main="test", scale=list(rot=60))
Basically it produces a graph of city on the x-axis and its associated revenue
on the y-axis. In the real data set, the x-axis will be filled of tens or even hundreds
of cities, so I wanna label the dots in the graph whenever the revenue (y value) is
greater than a threshold, let's say 90 in this case. The labels should be in (x,y)
format, which is (Atlanta, 100) in this case. Appreciate a lot for your help!
dotplot(y~x, xlab="Store", ylab="Revenue",main="test",
??????? xlim = ifelse(y > 90, sprintf("(%s,%g)", x, y), ""),
??????? scales=list(rot=60))

Best,
Tony

Hi Deepayan,
Thanks for the hint. I spent some time on the research but haven't got any luck in writing the custom panel function for the conditional labeling of points in a graph. Could you please provide some more thoughts and probably some pseudo code? Thank you so much for your time!
I'll be happy to try if you provide a reproducible example.
