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="", col="red" ) axis(1) Jim On Wed, May 9, 2018 at 9:00 AM, Gregory Coats <gregco...@me.com> wrote: > I do not see any difference between the x versus y plot drawn in blue, and > the y only plot drawn in red.
