The demand value is the average power [kW] consumed during the demand
period (typically 30 minutes), and is used in power company transactions.
The demand graph is refreshed after each demand period. A bar graph is
displayed at the start of recording, but for long-term recording, the display
changes to a fluctuation graph.

Scrolling is useful for analyzing
the display after magnifying the
vertical axis.
The interval and demand period for a time series graph can be set independently.
So there are some cases where the recordable period for the time series graph
and the demand period are different (p. 155).
