Thank you for that,<div><br></div><div>I have put some configuration into /etc/collectd/collection.conf on the server where the data is collected and the graphs are drawn, however, the graphs do not change at all, even after completely deleting what is there.</div>

First I should mention that collection3 is not supported [1][2].<br>
Nonetheless I will give you some hints. You can find all of the<br>
following information in the perl-scripts of collection3.<br>

</div>You can change the "ping" type in the etc/collection.conf file to<br>
use the "GenericStacked" module. Furthermore you have to disable the<br>
"stacking" so that the different ping values are not summed up.<br>
<br>
E.g.<br>
…<br>
<Type ping><br>
Module GenericStacked<br>
Stacking false<br>
…<br>
</Type><br>

<br>
Rrdtool graphs the data and you can give additional options to it<br>
with the "RRDOptions" switch. ( man rrdgraph )<br>
In your case the "-u" and "-l" options should do what you want.<br>
E.g.<br>
…<br>
<Type wireless><br>
RRDOptions -l -100<br>
…<br>
</Type<br>
