How do I compare two periods?

Pick a range and a granularity, and the statement renders a column per period: days, weeks, months or years, side by side, with a change column between them. The comparison is the same thirty-four lines rather than a separate report, so a difference can always be traced to the line that caused it.

Wide tables drag to pan rather than scrolling in a box, which keeps the line labels in place while the columns move.
