This indeed needs to be looked into. I am guessing that 1D masks are part of the SasView 1Ddata object structure? though not even sure of that since most early 1D formats do not include masks for 1D data. But masking in general was not something that was thought of much in the original SasView implementation. It was added for 2D fitting but there is nothing added for 1D (and arguably even less necessary for 1D reduced data than 2D?). The NXcanSAS format does allow for masks so should be able to respect that. Guessing however we can move this to 5.1

The 1D data structure has no concept of masks. The mask object for the 2D data was built into the parent plottable_2D class but was never implemented in plottable_1D. Once the mask is added to the plottable class, passing it to the GUI and perspectives might need to be added.
