Hi,
Have a look at this example in plot.zoo:
## Custom x axis labelling using a custom panel.
# 1. test data
z <- zoo(c(21, 34, 33, 41, 39, 38, 37, 28, 33, 40),
as.Date(c("1992-01-10", "1992-01-17", "1992-01-24", "1992-01-31",
"1992-02-07", "1992-02-14", "1992-02-21", "1992-02-28", "1992-03-06",
"1992-03-13")))
zz <- merge(a = z, b = z+10)
# 2. axis tick for every point. Also every 3rd point labelled.
my.panel <- function(x, y, ..., pf = parent.frame()) {
fmt <- "%b-%d" # format for axis labels
lines(x, y, ...)
# if bottom panel
if (with(pf, length(panel.number) == 0 ||
panel.number %% nr == 0 || panel.number == nser)) {
# create ticks at x values and then label every third tick
axis(side = 1, at = x, labels = FALSE)
ix <- seq(1, length(x), 3)
labs <- format(x, fmt)
axis(side = 1, at = x[ix], labels = labs[ix], tcl = -0.7, cex.axis = 0.7)
}
}
# 3. plot
plot(zz, panel = my.panel, xaxt = "n")
Regards,
Jose

Subject: [R] Can't format x axis on a stacked plot of a zoo object
As an example data set:
set.seed(1)
z.Date <- as.Date(paste(2003, 02, c(1, 3, 7, 9, 14), sep = "-"))
z <- zoo(cbind(left = rnorm(5), right = rnorm(5, sd = 0.2)), z.Date)
tt<-time(z)
fmt<-"%b-%d"
labs<-format(tt,fmt)
plot(z[,1], xlab = "Time", ylab = "")
If I plot the data and don't like the format of the x axis I can do this:
plot(z[,1], xlab = "Time", ylab = "",xaxt="n")
axis(side=1, at=tt[1:5],labels=labs[1:5],cex.axis=0.7)
But if I want to do a stacked plot:
plot(z, xlab = "Time", ylab = "",xaxt="n")
axis(side=1, at=tt[1:5],labels=labs[1:5],cex.axis=0.7)
The axis command has no effect. Can someone explain what is going on and how to
format a stacked plot like this?
Thanks
