Sounds like you're looking for an 'xload'-type scrolling net throughput
graph. I don't have one of those, but I can always monitor my connection
using xosview.
The first, and most painful, step, is to compile your kernel to include IP
accounting. Regardless of what tool you use for the monitoring, you will
likely need this in your kernel, so it's got nothing much really to do
with xosview.
To make the net portion of xosview work for you you'll want to set some
resources. Here are the ones I have in my ~/.Xdefaults to monitor a 28.8
connection, along with some nice colors (the 8000 sets the kB/s that
corresponds to a pinned scale. With a faster connection you'll certainly
want to change this number.

Finally, to turn on the IP accounting you need to use ipfwadm. I do that
by putting the commands in /etc/ppp/ip-up.local, which is run whenever my
PPP connection starts. Here's that file:
--
#!/bin/sh
# Here are the command line variables:
#
# Arg Name Example
# --- ---- -------
# $1 Interface name ppp0
# $2 The tty ttyS1
# $3 The link speed 38400
# $4 Local IP number 121.212.196.225
# $5 Peer IP number 121.212.196.221
# Set up IP accounting
/sbin/ipfwadm -A -a -S $4 -D 0/0
/sbin/ipfwadm -A -a -S 0/0 -D $4
--
If you're not using PPP you can just put these commands somewhere else
that makes sense. If you don't feel like using xosview, oh well.
