bug(aggregators): first (empty) item should be skipped

[PrastoDj]

Hi, using aggregate function delta, the first bar displays always the value 0. It's like it uses the > instead of >= in lower bound hours_to_show parameter.

Thanks for your support

It's also the same issue with aggregate_func: diff. @jlsjonas @RomRider is there any chance you could look on this?
