Unfortunately no. The charts are derived directly from the database so cannot be intercepted. You would need to store the difference values in the database.

Hi Peter,
I had the same challenge and created a virtual devices for water, gas etc (for each hour/day/week/month you want to graph). That virtual device holds the counter reading from yesterday in the devicevalue. At 00:00 hours you update the devicestring with the delta between the current value and yesterdays value and store the current value in the devicevalue. Then use manual update the database table and read the value from the devicestring.
It takes some light scripting to do but is not difficult
Regards,
Bart

I use this charting plug-in to chart my current gas and electricity usage as read by RFXCOM. There is also a virtual device that holds the daily usage.
I have added this device as chart source, but I only receive 0 as value.
It seems this device is reset, just before the chart reads its value at 0.00h.
Could you add another timer for 23.59.59?
Or is there another way to read this daily usage value?
