Dear Experts,
I generated the plot attached. Every other thing is OK except the black
horizontal lines which should appear like points or dots as the coloured
ones. I can't understand why.

I tried to change it to look like dots by calling empty plots so that I
will add them as points.

Since I have a range of date that can fall any where within 2005, I tried:

plot(1, type="n", xlab="", ylab="",
xlim=c(as.Date("2005-01-01"),as.Date("2005-12-31")), ylim=c(-.5, -10))

ylim worked fine but xlim instead of appearing like date as indicated on
the x-axes of the attached plot, translated to ordinary numbers (12800,
12900,13000, 13100).

All the data is of the same format:
2005-01-04 -2.76105935648091
2005-01-19 -9.60813496025994
