This looks amazing! thanks I will review it and let you know any observation. |
Yes, please do! I used FindHitPoints to get the closest ChartPoint, but I bet those calculations have already been done by the ToolTip finding logic. Maybe this functionality can be hooked into that. |

There was a problem hiding this comment.
This is the only thing I don't completely like, we do not need to calculate the index, instead I think that the library should expose a read only property where we can get this value, The library internally can assign this index, there is no need to go and find it every time the crosshair is invalidated.
We can build that in a new PR, for now this seems ok.
Created a way for making the crosshair "snap" to the closest available ChartPoint. Can be enabled/disabled on a per axis basis
