This is merely a hint to developers of LabVIEW:
The "waveform" data accepts some variant additional information that is generally rarely used (e.g. not any graph shows NI_UnitDescription strings).
It would be a good idea to have some sort of "error of measurement" (or "measurement deviation") attached, e.g. as a constant and a multiplier or an additional waveform. This error should be propagated and re-calculated inside addition, multiplication etc. numerical elements, and should be displayed in graphs as a shade of final tolerance (or line width). This will help to estimate the quality of a measurement without much programming efford needed today.
