Combine Solar and Powerusage graph

[Dimmi]

Hello,

I'd like to see a graph with my solar and power usage data combined. As far as I know this is not yet available.
Data I like to see in the graph:
Power taken from the grid (positive)
Power given to the grid (negative) This is now also shown positive in the Smart meter graph, what might work a but confusing I think.
Solar power generated (negative)
Own usage =Solar power + Taken from grid - given to grid (positive)

I think that a graph like this gives a better idea of your real power consumption.
