Describe the solution you'd like

Add a label to the left of the chart or in the top left of the graph, this should be user definable, for example a user may want to label network as LAN, WiFi, Net, etc.

something like this but with labels for the other graphs

Describe alternatives you've considered

adding 5 instances of the widget and using do-it-yourself-bar to add labels between them as separate widgets, but this seems like it would be inefficient
