plot using lines wraps around

Show all headers | View raw

I'm plotting using the following command:
plot "$p" using 2:6 title "IOPS" with lines lt 3 axes x1y1, \
"$p" using 2:9 title "Service Time" with lines lt 4 axes x1y2

The plot seems to create a line from the last entry to the first entry
as if it continued from the first entry again. The complete gnuplot
commands are as follows:

#

set terminal png small size $W,$H
set output "$HOSTNAME/$PNG_PATH/sa$day_name.2.$device.multiplot.png"

#set format x ""
#show format

set style data lines
set title "Disk IOPS vs Service Time, for Day => $day_name, for device

set yrange [0:100]
set ylabel "% Busy" tc lt 2
set rmargin 9
show title
plot "$p" using 2:4 title "Busy" with lines lt 2 axes x1y1

unset multiplot


Any ideas as to what I'm doing wrong that would cause the plot to
wrap?

I'm using:
