[rrd-users] Newbie question

[jdidron at tripnotik.net]

Hello list,

A newbie question follows ;o)

I'm making stats on my network if (you can access it here : 
http://www.tripnotik.net/testing/data/rooter_net_traffic.png ).
As you can see on this page, I represent download on top and upload at 
the bottom (multiplying it by -1).
The problem is that on the y-axis grid, numbers show negatives for 
upload, and I want it positive ... Is that possible ?

here is my  rrdtool graph :

    rrdtool graph "${GRAPH2}" \
        --start $i --imgformat PNG \
        --vertical-label "Traffic sur eth1" \
        --units-exponent 0 \

Thank you in advance for any tip you can give me ... and sorry if my 
explanation is unclear.
