Solution
This seems to do the trick!

HTML Code:
#!/bin/sh

#This file calculate the local maximum values in the second column 
#of a file consisting of two columns and creates a file of this data.  
#
#$1 represents the first input variable:  the input file
#$2 represents the second input variable: the output file

input_file=$1
output_file=$2
i=0
j=0

 while read line
   do
   i=`expr $i + 1` 
   eig[$i]=`echo $line|awk '{print $1}'`     #eig and strain are arrays from 1 to length of file
   strain[$i]=`echo $line|awk '{print $2}'`
 done < $input_file

eig[$i+1]=0
strain[$i+1]=0

while [ $j -lt $i ]; do
   j=`expr $j + 1` 
   if [ j == 1 ]; then 
      if [ ${strain[$j]} -gt ${strain[$j+1]}  ]; then
         echo ${eig[$j]} , ${strain[$j]} >> $output_file
      fi
   else
      if [ ${strain[$j]} -gt ${strain[$j+1]} ] && [ ${strain[$j]} -gt ${strain[$j-1]} ]; then
         echo ${eig[$j]} , ${strain[$j]} >> $output_file
      fi
   fi
done

wmnd

WMND(1) 						      General Commands Manual							   WMND(1)

NAME

       wmnd - WindowMaker network device monitor

SYNOPSIS

       wmnd [ -v | -h | [ -d display ] [ -i interface  ] [ -w ] [ -b ] ]

DESCRIPTION

       wmnd(1)	is  a WindowMaker dock application that shows a graph of the network traffic of the past few minutes, current activity and current
       and overall send and receive rates. Additionally it can launch any program in response to mouse clicks.

       There are two modes for the max-meter (the one on top of the graph).  Per default it shows the maximum value on the graph. The second  mode
       shows the maximum value of a historical record since wmnd was started. You may left click on max-meter to switch modes, right click on max-
       meter to hide the max-meter.

OPTIONS

       -i interface
	      Start showing the status of network interface interface.

       -w     Draw the graph in waveform mode (default is inverse waveform mode). Right clicks cycle through all available modes.

       -b     Scale the values of the maximum and current rate by factors of base 2 instead of the default 10-based scaling. (1K  equals  1024	in
	      binary mode, but 1000 in decimal mode.)

       -h     Show summary of options.

       -d display
	      Draw onto X11 display display.

       -v     Show version of wmnd.

USAGE

   Active Interface
       You  can  cycle	in  realtime through all available active interfaces by simply left-clicking on the interface name gadget on the upperleft
       corner of wmnd.

       The 'lo' interface is an exception, 'lo' ONLY works when invoked from the commandline (wmnd -i lo), lo was mainly built in for testing pur-
       poses.

   Device Name
       By  default,  wmnd show device name in short term of four characters, for example, the ippp0 will be displayed as ipp0.	You can toggle the
       device name between short and long by right-click on it.

   Graphic Mode
       Left-click on the main graphic area to cycle the graphic mode.

   Max Meter
       Left-click to toggle the history max or screen max, default is screen max when wmnd is startup.	Right-click to hide or display.

   Byte/Packet Mode
       Left-click on the letter gadgeted on the right-top corner can switch between the Byte or Packet counter mode. "B" for byte, "p" for packet.

   User Script
       Click on the bottom rate meter can invoke the user command defined in resource file .wmndrc.

   Dragging WMND
       Be sure to drag WMND on it's outer edges, it's a bit picky due to the large gfx pixmap it keeps. You can also  use  a  keyboard	and  mouse
       shortcut (perhaps ALT+left-click) in your window manager to drag it around.

FILES

       ~/.wmndrc User configuration.

       The format of this file is:

	      # WMND configuration file

	      # middle line in wave mode color
	      md_color=#71e371

	      # RX/TX color (can be #xxxxxx, or color name from rgb.txt)
	      rx_color=#188a86
	      tx_color=#00fff2

	      # refresh between status polling (not graph scroll speed)
	      # numbering in nanoseconds
	      refresh=50000

	      # bar graph scroll speed (in seconds)  this setting also affectsi
	      # the rate and max speed displays.  the longer the delay, more
	      # inaccurate these are since the max and rate values are averaged
	      # across this interval
	      scroll=1

	      # buttons for user scripts
	      # bt1_action=su -c ethereal
