Nagios graphs problem



I have a problem with check_load over nrpe and generating graphs.

For the same commands system generates two two different output and I can’t spot where is a mistake.
I am checking check_load for two hosts (in my commands.cfg I have):
define command{
command_name check_load
command_line $USER1$/check_nrpe -H -c check_load
define command{
command_name check_load_db
command_line $USER1$/check_nrpe -H -c check_load

First of it gives me:
OK - load average: 0.49, 1.43, 1.49|load1=0.490;15.000;30.000;0; load5=1.430;10.000;25.000;0; load15=1.490;5.000;20.000;0;
OK - load average: 0.10, 0.14, 0.10|load1=0.100;15.000;30.000;0; load5=0.140;10.000;25.000;0; load15=0.100;5.000;20.000;0;

Ok syntax is the same.
But in first case I am getting one chart with three variables, in second three charts with (load1, load5 and load15).

Any idea why it happens?
