Hi Greg, Easy: plot (x_yyyymmdd, y_duration, type="l", xaxt="n", yaxt="n", ylim=range(240,480)) abline (h=c(240,270,300,330,360,390,420,450,480,510,540), lty=2, lwd=1.0, col="grey40") axis(1,at=x_yyyymmdd,labels=format(x_yyyymmdd,"%Y-%m-%d")) axis(2,at=seq(240,480,by=60),labels=c(...

...Thank you very much! How do I use the axis command for side=1 to label the x horizontal axis, in the format="%Y-%m-%d? style?

Hi Greg, What you are getting there is a factor, interpreted as a 1:n sequence based on the sort order of your "dates". Here's a way to get dates on your x-axis in the format you want: x_yyyymmdd<-as.Date(c("2018-04-25","2018-04-26","2018-04-27", "2018-04-28","2018-04-29","2018-04-30","2018-05-01","2018-05-02", "2018-05-03","2018-05-04","2018-05-05"),format="%Y-%m-%d"...

Thanks. Regarding axis(1,at=x_yyyymmdd,labels=format(x_yyyymmdd,"%Y-%m-%d")) How do I get the text for YYYY-MM-DD to be drawn vertically, instead of horizontally?

...365.64366, 317.26150, 321.71883, 342.44950, 318.95350, 322.33233, 330.60333, 428.99516, 297.82066) plot (y_duration, type="l?) Adding Year-Month-Day values for the x axis, and then calling plot (x,y), yields a bizarre plot. Apparently, R does not understand my Year-Month-Day values. x_yyyymmdd <- c (2018-04-25, 2018-04-26, 2018-04-27, 2018-04-28, 2018-04-29, 2018-04-30, 2018-05-01, 2018-05-02, 2018-05-03, 2018-05-04, 2018-05-05) plot (x_yyyymmdd, y_duration, type="l") I would be enormously appreciative of your guidance.

Jim, That you very much! How do I instruct staxlab to label once every n days, rather than labeling every day? Greg > On May 5, 2018, at 6:50 PM, Jim Lemon <drjimlemon at gmail.com> wrote: > > staxlab(1,at=x_yyyymmdd,labels=format(x_yyyymmdd,"%Y-%m-%d")) [[alternative HTML version deleted]]

...labels that would overlap. When you have labels that are all the same length, this usually results in every second, or third, or fourth label being displayed. So you can probably get what you want by not using staxlab. However, if you really want to use staxlab, try this: oddones<-seq(1,length(x_yyyymmdd)-1,by=2) staxlab(1,at=x_yyyymmdd[oddones], labels=format(x_yyyymmdd,"%Y-%m-%d")[oddones]) It will also work with plain "axis", which is what you seem to want.

Look at par(las=2) in the graphics package. You will almost certainly have to increase the bottom margin, e.g.: par(mar=c(6,4,4,2) to accomodate the vertical labels.

Hi Greg, This is because both plots have equally spaced x values. To see the difference, try this: plot (x_yyyymmdd, y_duration, type="l", xaxt="n", yaxt="n", ylim=range(240,480), xlab="", ylab="", col="blue") axis(1) plot ( y_duration, type="l", xaxt="n", yaxt="n", ylim=range(240,480), xlab="", ylab=&q...
