Scaling ucd/net CPU usage graphs

[MuddyMagical]

I have added three hosts with the ucd/net CPU Usage Graph template, but there is a difference in the scaling of the graphs as shown in the attachment below.

In the Cacti logfile i get these entries:

09/10/2012 08:40:04 AM - POLLER: Poller[0] CACTI2RRD: V:/rrdtool/rrdtool.exe update V:\Apache2\htdocs\cacti\rra\node_33_-_a_cpu_system_207.rrd --template cpu_system 1347259204:4289878
09/10/2012 08:40:04 AM - CMDPHP: Poller[0] Host[13] DS[207] SNMP: v2: 10.***.**.***, dsname: cpu_system, oid: .1.3.6.1.4.1.2021.11.52.0, output: 4289878

09/10/2012 08:40:03 AM - POLLER: Poller[0] CACTI2RRD: V:/rrdtool/rrdtool.exe update V:\Apache2\htdocs\cacti\rra\node_11_-_b_cpu_system_195.rrd --template cpu_system 1347259203:9639
09/10/2012 08:40:03 AM - CMDPHP: Poller[0] Host[11] DS[195] SNMP: v2: 10.***.**.**, dsname: cpu_system, oid: .1.3.6.1.4.1.2021.11.52.0, output: 9639


How do i get the graphs to have the same scale?
