Graph hover tooltip time precision

Hi all,

I’m trying to understand the logic behind when the graph panel tooltip shows milliseconds, and when it doesn’t. I’m running the latest 6.3.5 at the time of writing.

I’ve attached below two screen captures of the same dataset, at the further out zoom I get milliseconds, but when zoomed in further (when one would naturally expect to get more time precision) the sub-second component disappears.

Is there any way to force the fractional second component to always display? It’s really necessary for my application.

Thanks
