Is there a way to keep gas price history with the date, so as gas prices change the savings difference can be seen over time?
My example would be
2/22/19 Gas at $2.21/gal so savings is $x.xx
but if I change it on 3/5/19 and gas is $2.48 the old data stays with the date/gas rate but the new data is updated with that gas savings rate.
