InstrumentView pixel count summation shouldn't need an x range to be set on the workspace

Description

It appears that you cannot view the integrated pixel counts in the instrument view if there are no bin boundaries set on the workspaces - you just see an all-white instrument.

I'm fairly sure this didn't used to be the case and it shouldn't be necessary. It would be nice to be able to start up a live listener with not processing, show the instrument and watch the counts build up, but right now you can't unless you put in a call to Rebin.

Raised in priority as this is a common action for live data viewing and just confuses people.

I'd failed to notice something when I wrote this ticket - I'd unchecked 'Preserve Events'. If you keep the events then the instrument view is OK. If things are converted to a Workspace2D without any processing at all then you get the default X boundaries of an EventWorkspace (0 and a tiny +ve number). That's when you get the all-white instrument view because all the events are outside these X values.

This may not be what I'd like to happen in this specific situation, but in the general situation it's the correct behaviour. I'd recommend closing the ticket as invalid.

I agree - this was my mistake.
