History Graph
We needed a chart of activity over days, like sessions per AI tool each day, that works for a week, a month or two months.
A new shared chart draws each day as small stacked squares, one lane per series. It scales from a week to two months and is documented with many examples.

What changed
The two changes that matter most, in plain words. Open any one to see it.

When numbers get big, each square counts for more, and past forty days the squares become thin bars.
One chart from a week to two months
- Each series gets its own lane in a day's column, rather than all of them piled into one stack. In words
- The chart's colours live in one short file that's easy to change, and they're checked to read well in light and dark. In words
- Columns keep a natural size and only shrink when space is tight; squares are square, and their size and gaps can be set. In words
How we got here
Each change, traced back to the conversation it came from. A solid mark means the record names the source; a dashed one was matched by the draft and waits for review.

c87-D3 This cycle is exploratory and demo-only, with no wiring into the product dashboard. — Mark Parson
c87-D5 Series sit side by side in lanes within each day, not summed into one stacked column. — Mark Parson

Thanks to
People outside Qpoint first. Every thank-you points at something they said or made.
Set the sketch and steered its shape
Supplied the mock and the brief, kept the colours in an editable file, then caught the stretched columns, asked for square blocks and corrected the lanes to sit side by side.
