I'd suggest using four DS:<br>
<br>
(1) PV 0700-1900<br>
(2) PV 1900-0700<br>
(3) Supply 0700-1900<br>
(4) Supply 1900-0700<br>
<br>
When updating the RRD between 0700-1900, record the values in the DS's<br>
for (1) and (3), recording zeroes as values for the other two DS'es.<br>
And, vice versa when the time is between 1900-0700. Make sure to record<br>
zeroes and not unknown ("U").<br>
<br>
Then, you can graph all four DS'es, each with their own colors.<br>
