Dear All: I have the following data: 0 100 0.5 79.9605 0.75 84.7098 1.5 72.1793 2.5 97.4924 4.5 90.9696 8.5 59.9794 24.5 76.4859 456 100.0000 457.5 116.7381 460.5 118.7550 464.5 89.5898 480.5 86.3348 left column is time and right column is concentration, I would like to plot all data on one plot, however, if I specify xlim=c(0,500), there will be a very long distance between points 24.5 and 456, what i am thinking is to make two days(0 and 19 days) very close on the plot and use a kind of "//" sign on the x axis to seperate the x axis. no work needed on Y axis. I hope I clarify my question and thank you very much for your consideration and help in your busy time. Zheng [[alternative HTML version deleted]]
Check out gap.plot in the plotrix package.
