Hello Mr Jung,

1-2) You must enable the data breaking in the series. You can select which value to use for breaking (not just NaN), and is it enabled or not.

Please see LightningChart User's manual, section "DataBreaking by NaN or other value" for details. And also check Demo application's example "Line Breaking by NaN", it'ss one of the very first examples in most of the demo applications.

If you feed NaNs and series.DataBreaking is not enabled, it will draw crazy lines, or no lines at all. For performance reasons, we recommend keeping DataBreaking enabled only when you know there's going to be NaNs in the data.


3) If series hide when you are zooming, it means typically that you have invalid data in your series. Invalid data is e.g.
- using NaNs when DataBreaking.Enabled == false,
- using descending PointLineSEries X values. The X values must be same or grow all the time. PointLineSeries is a progressing series .

I hope this helps :)
