Some problems with units

Hi,

First of all thanks for this amazing plugin. It really helps me a lot.
However, I have one problem with the units used by the plugin.
I use this especially for Nagvis.
In the host list, and on the host view all works perfectly but in nagvis, on my weatherline, the unit is always in Bytes.
I tried options (-u) and also to modify the plugin config but no way to get those units in megabits or gigabits for example…

Can someone help me about that ?

Thanks again for sharing this plugin!
