A dated time series, explained with context.
A fictional refill pilot. Actual dates, consistent units, a zero-inclusive scale and a careful interpretation. The edge example begins at zero and uses irregular observation intervals.

The Reuse Observatory · No. 06 / 2026. Small returns. A growing habit. A fictional neighborhood refill pilot, observed over six months.
Weekly refill activity: Completed refills in the observed week. Counts, not unique customers.
The full picture, over time. The line uses proportional date spacing and a scale that includes zero. Change over the complete observation window: +38 refills / week. Relative change: +82.6%.
A habit takes shape. This sample illustrates a trend. It does not establish why activity changed.

The boundary example
Zero baseline, uneven date spacing, truthful absolute change.

The Neighborhood Ledger · Pilot / 2026. A new service starts from zero. A fictional lending desk begins a short pilot, with a small first set of observations.
Completed daily loans: One completed loan is one recorded checkout. Returns are not counted as new loans.
A small start, shown in context. The line uses proportional date spacing and a scale that includes zero. Change over the complete observation window: +12 loans / day. No percentage change is presented because the baseline is zero or negative.
The first steps are visible. The starting value is zero, so a percentage growth figure would be misleading. The increase is 12 loans per day.
