Each point is one sale of tracked sats, found on chain by the fork: a marketplace listing or an accepted offer paid in the same transaction. Its price is the marketplace's: on Magisat the listing price, the seller's payment plus Magisat's 0.5% seller fee since September 2024 (the buyer's fee is not in it), and for an accepted Magisat offer the payment plus half the fee output; elsewhere the seller's payment plus the marketplace's fees. Sales with no marketplace fee in the transaction (OKX's, among others) are Unknown.

The unit price is the price less the sold output's own value, per sat of a row. Each sale is of one row, the rarest that holds all the sats it sold, so rows don't overlap: Uncommon is plain uncommons (a 2012 uncommon is an Alpha uncommon, a rare sat a Rare), Block 9 is block 9 chunks (a 450x chunk is 450x). A bundle that mixes rows is of its rarest row. A label row, such as Block 9, 1st tx (a label within Block 9), has no market of its own: it lists the sales lying in it, each as its own row. Include rarer sub-categories also shows a row's rarer sub-categories, such as the alpha uncommons under Uncommon: lighter, priced per sat of the row, named by their own, and outside its median and market numbers. A sale that splits sats out of an output counts only the sats it sold. A sale for no more than the output's own value has no unit price above zero: it is in the table, not on the chart.

The line is the row's median unit price over the 30 days up to each sale. Outliers, drawn hollow, sold for over 10 times or under a tenth of the median of the row's previous seven sales: a fat finger, a wash trade, something else in the output. They are left out of the line and the row's market numbers. Inscribed sats carry an inscription, whose value is not the rare sat's: hidden unless you include them, and never in the line.
