Can I get Crosshair Values?

[Ceweiss42]

I've been working on a data charting application using this library as the core charting system, but have run into a problem regarding the crosshairs.

Currently, my application looks like this:

The problem is that while the crosshair has the value displayed on it (572 in this case), I want to be able to use that value on my own (to update those zeroes in the top right of each panel by getting the line value at X=572). However, I cannot seem to find a way to access the crosshair label values. Is there a way to do this?

This also seems like it could be possible with tooltips, and I tried getting there with a custom tooltip but ran into a problem with getting the legend to receive those values
