I have some bogus data in the system overview causing wrong graphs.
It would be very nice to have an option to delete bogus data.
Sorry. Not currently possible.
Usually due to third party customisation or modifications.
Probably due to external ac loads which in nodered where initially set to 0 kWh before receiving the first kWh value.
Anyway, maybe the delete option can be added to the feature request list?
I’m having exactly the same problem.
I installed the OpenDTU Modbus integration; unfortunately, it had a bug that has since been fixed.
Because of that, I’ve got almost 100 kWh of solar generation and corresponding consumption recorded in the data from 10–20 restarts 
Is there anything planned to allow these kinds of peaks to be deleted?
We’ve heard nothing to that effect. Only that it isn’t something that can be (currently) done.
