This has come up a few times. Users really want to be able to show more than a single decimal place in the RT annotations on chromatograms. Seems like this could be easily added to the Properties form for the chromatogram graphs with a single edit box.

What would we want to call the new control? "Retention time precision"? "Peak RT digits"? etc?

Do we insert it above the "Graph area dimensions" control?

Does this setting apply to just the peak notations, or does it also apply to the RT axis values? (NOT the axis, I hope, since those are currently automatically and reasonably determined)

Not the axis. Just the annotations. You can actually zoom in and get any level of precision you want on the x-axis.

I think above the "Graph area dimensions" would be good. I would not us the RT abbreviation here, even though it is tempting to reduce the length of the label, but the axis says "Retention Time".

I guess I would use "Retention time annotation digits:" It is a long one, I know. If you use "precision" then you would need to add the word "digits" after the edit box to clarify what the number actually is, because "precision" is 1 or 2 or 3 doesn't make sense without the "digits" to clarify what the number really is.
