Message:
  • Upraveno: Skripty pro načítání hodnot byly pročištěny a přepsány na třídy. Pro definici místně měřených veličin nyní použita tabulky MeasureClient odkazující se na tabulku MeasureMethod obsahující globální registr měřících metod.
  • Opraveno: Různé chyby vzniklé při přepisu třídy Measure a použité pro zobrazení obrázku grafu.
