Recalculate energy tab

Today i switched from HB to HA and made a small mistake in the calculation of the Power Costs.
Instead of .24 cents I accidently had 24€/kWh. I corricated that price but does it effect the statistics and if not is there a way to let HA recalculate that?

If i cannot recalcuate is theyre a way to empty the chart for today?

Kind regards,
