We have a chart that display some metric over the time category axis. We want to correlate the metric data with another widget on the page. For this we need to be able to receive the current position of the crosshair on the time category axis. So the question is - is it possible to subscribe to the crosshair tracking (or some other event) to receive the datetime value from the time category axis when position of crosshair has changed.

Also, when we use time category axis (Date values) and set the baseUnit: "seconds" then chart still shows and plots values only on minute marks. Is there a way to make it more granular (actual seconds) over the datetime axis?

We figured out the second part of the question, related to the scale of the category axis. But we still have not found a solution for tracking crosshair...

Hello,

Sorry for the delay.

I couldn't think of anything better than hacking the tooltip template, but what's really needed here is a plotAreaHover event.
Should work in a similar manner to the current plotAreaClick event.

I've added it to our to-do list for the Q1 2016 release that is due in January.

I hope this helps.
