Group individual monitor devices in Energy Panel

Hi HA community
With the new energy panel (thanks HA to add recently water), we can follow individual devices.
Is there possibiity to have peak/offpeak in the same line with different color as the global energy ?


In this capture, two last lines are the same utility_meter with 2 tariffs
I saw in a youtube video but i don’t try to found it again, the aim of have two bar lines for one device

Other question is there a possibility to get circular diagram (for exemple) with showing of consumption or repartition in % by group (light, heater, pool,…). I think i can add sensor helper to add consumtion by group. But how render the graphical ?

Finally i’d like to have a dashboard style near plugin info conso in jeedom
