Excellent, that looks very nice!
I had not realised that plotrix would do that and I
was definately hesitating to try and figure out how to
do it myself.
Any idea why all I was getting was a single date on
the x-axis when just doing plot?

Thank you. Almost too fancy for the target user but
very nice indeed. For some reason I had not thought
of using ggplot2.

Thank you Jim. That does give better results. I had
not realised how complicated a question I was asking.
Both yours and Jim Lemon's solutions work very nicely.
I am still messing up the syntax with Gabour's
approach. Thanks to all for the fast and valuable
help.

You can get a slightly better X axis by converting your Date variable to chron:
Replace this:
plot(mydata[,1], ...)
with this:
library(chron)
plot(chron(unclass(mydata[,1])), ...)
and ignore the warning.

I am completely misunderstanding how to handle dates.
I want to plot a couple of data series against some
dates. Simple example 1 below works fine.
Unfortunately I have multiple observations per day (no
time breakdowns) and observations across years.
(example 2 very simplistic version )

Now your first data point is 9/26/09; is it supposed to be 9/26/06?
