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)
