Field notes
The site frames CSV Compare Chart as a focused alternative to both dense spreadsheets and full business-intelligence platforms. Its documented workflow includes period comparisons, normalization, smoothing, frozen inspection points, and chart-image export. A separate installation combines current energy readings with historical context on a dedicated small monitor, while the workflow section names local collectors and shared CSV or JSON histories as possible upstream inputs.
