ticks

I was wondering how I could plot more tick marks when plotting time on the x-axis.

Basically, a time equivalent to pretty. Pretty obviously doesn't work so well with times, as it uses factors of 1,2,5 and 10. For time one probably wants e.g. hours, half hours, ...

plot(as.POSIXct(x,origin="1960-01-01"),y,type="l",xlab="Time")

gives really too few and widely spaced tickmarks.

zoox<-zoo(y,as.POSIXct(stats$Time,origin="1960-01-01"))
plot(zoox)

gives the same.

Thanks

I have to plot many lines in GNU PLOT.No problem with the X axis. The problem that I am facing is that most of the plotted lines are at yscale [0-0.05] ,few at range 60-70 and rest at 600-700. These numbers correspond to the y axis scale values. But after I plot I can see only 3 sets of lines all… >>> More
