Gnuplot Min and Max label

[teddym]

Hello,

I would like to know what to add on my script to display the Min and Max of my plot as label by using gnuplot script.

Here what my input file looks like:
69 17:58:31
44 17:58:32
87 17:58:33
173 17:58:34
69 17:58:35

In this example my min=44 and my max=173

Here is my script.
Citation:
set terminal png size 800, 600
set output "tick_time.png"
set xdata time
set nologscale; set nologscale y
set title "Bandwidth Mesurement Kbytes"
set timefmt "%H:%M:%S"
set xtics 600
plot "bptable" using 2:1 title "Average bp per second" with lines lt 3, \
"bptableavg" using 2:1 title "Average bp per minute" with lines lt 1

The easiest way would be the stats command.

Try
plot "filename" u 1
print GPVAL_DATA_Y_MIN , GPVAL_DATA_Y_MAX
