linux_system: the Network graph seems to be misleading (number of bytes per what?)

[x-yuri]

Template: linux_system

Describe the problem
The Network graph displays the number of bytes sent/received per some arbitrary period of time that depends on windowPeriod. At first I thought it's the number of bytes per second. Isn't it better to display bytes per some fixed interval?

To Reproduce
Steps to reproduce the behavior:

1. Open the Linux System dashboard
2. Take a look at the Network graph

Expected behavior
I expect the values to have some clear (absolute, not relative) meaning. As it is the graph can only serve to show spikes, but not how much data is transferred.
