Producing cost bar graph from ever increasing kWh feed


I have an ever increasing feed showing gas usage in kWh.
I display 1/2 hourly and daily usage as Bar Graphs as recommended by @TrystanLea setting delta to 1 and using the appropriate interval. I could use scale to produce a similar bar graph of cost but I need to add in the daily charge of 16.80p per day ie 0.35p per half hour period. Is there a way of doing this?

Hello @ian unfortunately not currently an easy addition in the same way Im afraid. Needs an offset option in the graph window :slight_smile:
