Field notes
The examples span materials testing, semiconductor datasheets, survival curves, and pump performance, with controls for linear or log axes. The page also shows a hue-tolerance control for separating colored curves and describes reading bar means and standard-deviation whiskers. Full exports are presented as paid, while the free sample exposes only the first 10 rows of the active series.
