[rrd-users] need help with a graph

[LÉVAI Dániel]

Hi!

I need some help with a simple graph. To be honest, I don't really 
understand rrdtool, but I'm trying... really. :)

So, I have a working mrtg configuration, which gets data from an snmpd, 
and then creates an rrd file.The mrtg script runs every one minute.
 From this rrd file I want to create a graph.
I'm doing this:
/usr/local/bin/rrdtool graph cpu.png --imgformat PNG --end now --start 
now-259200s --width 1000 --title CPU DEF:ds0a=janos_cpu.rrd:ds0:AVERAGE 
LINE1:ds0a#0000FF

After this I get this graph:
http://leva.ecentrum.hu/cpu.png

My problem with this graph is that it has low resolution (for me).
I get the data every one minute, but in the graph it only shows one unit 
per half an hour. Is it possible to make it show one unit per one 
minute, or at least smaller than half an hour?
I hope I make sense :)

Thanks!

Daniel
