I have two columns of data displayed as a scatter plot in Gnuplot 5.4 (on Big Sur). Adding the mean of the second column produces a horizontal line at the appropriate value on the y-axis. However, the first column's mean also shows as a horizontal line at the value on the y-axis. Is it possible to have it instead display as a verticle line at the appropriate value on the x-axis?
stats 'sleep.dat' using 1 name "A"
stats 'sleep.dat' using 2 name "B"
set xlabel "Hours"
set ylabel "Events"
set title "Apnea Events/Hours of Sleep"
set xrange [3:9]
set yrange [0:4]
set xtics 0.5
set ytics 0.25
plot 'sleep.dat' lc 9 lw 5, A_mean lw 2, B_mean lw 2
