Suggestion example for use in grafana

I included energy prices with powerline transmission fee and compared with a couple of friends energy usage hour by hour consumption. Added tomorrows energy prices so easy to plan heavy power usage and avoid high energy prices. @bisand Please feel free to delete this post after read because it is not a tibber-api issue.
