Hi All, I am a relative newbie at R and I am trying to plot some intraday price data over a long period of time. I would like to use a weekday(only) scale for x-axis. Can anyone tell me how to go about this? When I plot just the prices it looks fine, but when I add in the Dates/Times vs prices - I get gaps on the weekends and holidays... by default R wants to use a continuous time scale inclusive of weekends i looked at zoo and gap.plot from plotrix but neither of these seem to do what I want... Any help is much appreciated Cheers -- View this message in context: http://www.nabble.com/Weekdays-only-on-x-axis-tp16732251p16732251.html Sent from the R help mailing list archive at Nabble.com.

If z is your zoo object then you plot it like this: plot(zoo(coredata(z)), xaxt = "n") and then add a custom axis using axis or Axis. Also the quantmod package has this type of graphics built in.
