   Hi ! 
   First of all thx for the library, started using it this week ! It's just awesome ! Easy to use, with customization and performance !
   
   I'm having a similar issue in my project
   https://codepen.io/test45/pen/RwKEBqN. Here's another sample if it can help ! With a bit more holes (null values)
   The unwanted behaviour can be seen zooming a bit in the chart and moving the x absis 
   
   As for Tmscer example, the problem seems only to appear when using LTTB sampling method, and when the algorithm is applied to the serie. When the zoom level allow to display all points on the chart, the problem disappear. Guess it as something to do with the algorithm handling null / undefined values in the serie.
   
   Sorry if the english is a bit messy !
   And thanks again for your work !
