This means RRDtool will have to take 24 rows, average them, plot
the column, redo from start for the next column.

This also means the previous RRA contains redundant information
as it also has 60 steps per row.

If you know you want to view day one of the year, eventhough it is
requested in december, get rid of the 3rd RRA.  In other cases: change
the amount of steps per row for the 4th RRA and adjust the amount of
rows accordingly.  For instance: RRA:AVERAGE:0.5:1440:365

If you want a finer granularity: RRA:AVERAGE:0.5:480:1095
and then you can have 8 hours per pixel column.
