Of course. If you want to see a graphic for one week, you get the graph
with all hours displayed but no points or lines for the times where the
values are UNKNOWN.
If the graph drops the whole timeframes of UNKNOWN data (not only the
values) the scale of the time axis would change. Uncool or even uncor-
rect.

I think not because an UNKNOWN value should neither be added to the sum
nor increase the number of added values.
