Read the day again — the charts follow the panels by themselves
Each furnace's panel over the last 24 hours — a point a minute: each reading's last value in the minute, as Logs → Furnace panels keeps it (kept for good). The line breaks where its panel was not read.
Carried on live as the panels are read (about every 2 s): the tiles roll to the latest reading, the chart's last minute follows it.
Shaded: the heats on the furnace, with their no. (the lab's while it is the one in use — Settings → App settings).
Pick the reading the charts show above them, or click a tile. Each chart has its own scale.
Hover a chart: every furnace at that minute. Drag across one to zoom them all; double-click it, or Reset zoom, for the whole day.
Changes show as they happen — a live connection to the server
Read over Modbus (Settings → Modbus) — about every 2 s.
