[Question] Snap cursor to previous point until moved over next point.

[vildantursic]

Hi,
First of all I want to thank you for all the amazing work!

I moved from ECharts to uPlot library and so far almost everything I had in previous one is reimplemented in uPlot except one thing. Snapping of the cursor on xAxis is a bit confusing, tbh I got lost with options and functions 🥲

There are two features that I am trying to implement.

• First one is to replicate same snapping as in Echarts where cursor snaps directly on next point if there is a gap [recording1]

• Second one would be more advanced. Snapping cursor on previous point until I cross next point. In short, to avoid snapping mid way (to avoid snapping when going over gap area).
  Is this possible with uPlot?
  I tried using prox and bias as { prox: 1000, bias: -1, skip: [null] } thinking that it would snap to closest previous one since bias is -1 but I'm probably wrong since it is not working 😄

Is it also possible to snap vertical dotted cursor on X axis like in [recording1], and if yes how?

Current implementation in uPlot is shown in [recording2]

Thank you in advance!

P.S.
Do you have any plans for documentation? I am willing to help with creating docs, I just don't want to do PR without any consultation and have it hanging forever in Github void 😄

Hey @leeoniya, sorry but had to ping you just to ask if this is even possible 😄 if it is not I am totally fine with it. Finally completed everything, and works great.
Also check last part/question about Documentation 😄 would really like to contribute on that part!
