Dashboard Network Widget - Ability to reverse incoming and outgoing on the graph

ec8c40424f28551c9b54d66124c1b55b5bb02f3e

Problem/Justification
I would like the option to switch the incoming and outgoing positions on the Dashboard Network widget.

Currently you can only have Incoming on the top and outgoing on the bottom of the line and I would like a widget option so I can reverse this.

Impact
In the current setup some people might not find the layout of the incoming and outgoing abrs logical as they work different.

User Story
No really much to say, sometimes I struggle with incoming on the top and outgoing on the bottom and would like the option to change it.
