changing the x axis labels in a time series plot
3 messages · Jim Bouldin, Rui Barradas, Hasan Diwan
Hello, Actually, axis() was doing its job, but you have xlim=1:100 and cannot expect to see points at x=1322:1421. The correct way would be to say that your time series starts at 1322 and that it records observations with a frequency of 1. Then plot it. Just look. I've nclude an axis(9 call to make sure it works as instructed, meaaning, at=Year. z <- cbind(1:100,100:1); Year = 1322:1421 zz <- ts(z, start=1322, frequency=1) windows() plot(zz, plot.type="single", xlab="Year", ylab="zz") axis(3, at=Year) Hope this helps, Rui Barradas Em 14-07-2012 10:54, Jim Bouldin escreveu:
OK, this has to be simple but I've searched through help files, mailing list archives and well, everything I could think of, and still no luck. I simply want to change the x axis labels in a time series graph, from its default numbering (which starts at 1 and increments by 1), to values I have in another vector, "Year". It has to be a time series graph, I don't want to have to use a scatter plot because there are many lines to draw. Example: z = cbind(1:100,100:1); Year = 1322:1421 windows() plot.ts(z[,1:2],,"single", xaxt="n", xlab="") axis(1,at=Year) This doesn't work, not any of the permutations I've tried with the various arguments to plot.ts and axis. Thanks for any help. [[alternative HTML version deleted]]
