Compare
Put up to six charts side by side on one clock. Stack them to keep each chart's own scale, or overlay their primary series as percentage change from the start of the range so a $1,000 price and a 5 GSol/s hashrate can share an axis. The selection lives in the URL, so a comparison is a link.
Overlay takes the first series of every selected chart, aligns them by date, and rebases each to 0% at the first day of the visible range. A line at +40% means that series is 40% above where it started; the lines are comparable in direction and relative magnitude but say nothing about absolute levels.
Charts with several panes (for example a price chart with a volume pane) contribute only their top-pane primary series. Stacked mode shows every chart in full.
Rebasing is sensitive to the start date: shift the range by a week and the whole picture can flip. Try two or three ranges before reading anything into a crossover.
Series that begin later than the range start (derivatives from mid-2025, NEAR flows from March 2025) rebase from their own first available day, not the range start. Percentage moves of a series near zero, such as a net flow, are not meaningful — use stacked mode for those.
