Question

I want to plot the graph for every hour of a 1 week time series. The X-axis should look like:

0  1  2  3  4 .....23  0  1  2 3 4....23  0 1  2  3 ....23............ 0  1  2  3 ...23
---Monday----          ------Tuesday----  ----Wedneday----.............-----Sunday-----

I don’t know how to set the xlim for that because I need the x-axis for each hour representation for 1 week. There will be 168 points (24*7=168) on the x-axis altogether.

Answer 1

Not exactly what you’re looking for, but my solution to the same problem was to use ggplot2… and overplot by day of the week – which showed me that Sat and Sun were distinct, but the other days of week were very similar in behaviour.

# some random data...
adf <- data.frame(day.of.week=rep(c('Mon','Tue','Wed','Thu','Fri','Sat','Sun'), 24),
      hour.of.day=rep(1:24, 7), y.to.be.plotted=runif(168))
qplot(hour.of.day, y.to.be.plotted, data=adf, colour=day.of.week, geom='line')
library(ggplot2)
qplot(as.integer(hour.of.day), y.to.be.plotted, data=my.data,
        colour=day.of.week, geom='line')
