status

Overview ¶

Command status renders the two charts a path coloured from a column is for: a measurement read against a limit, and a series read against the state of the thing that produced it.

Both bind a column with geom.ColorBy, the way a scatter always could. What differs is where the colour changes, and neither chart says — the scale does. A classed scale puts the corner on the threshold, interpolated between two readings, because when the limit was passed is the fact being reported. A named scale puts it on the row where the new state was first seen, because nothing was measured in between. See docs/adr/0049-paths-colour-in-classes.md.

It is executed by a test so that it cannot silently stop compiling or stop producing charts.
