Scatter and Model — Cabinet Cooling Curve
Measured temperatures with their standard deviations against a modelled decay, which is the commonest figure in an engineering report and the one this platform could not previously draw without a browser. The intervals name themselves as SD rather than leaving a bare ±, so a reader can tell them from a confidence interval by reading rather than by asking.
