ADDITIONAL SYSTEM INFORMATION :
JavaFX ver. 17.0.2, tested on Windows and macOS (pretty sure this occurs in Linux too), OpenJFX + OpenJDK (17.0.2 as well)

A DESCRIPTION OF THE PROBLEM :
I have created navigation in LineChart using lower and upper bound properties. I have drawn a step chart and when most left point goes out of chart bound chart is displaying weirdly. It is like point connects to pre-previous point instead of previous one that went out of bound. I can confirm that data property which contains points doesn't modified while that.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Draw a step chat
e.g. something like this

___┌┐__ ___
               └┘
2. Increase lower bound of X NumberAxis so that some left-side points go out of bound
3. You will see something like this on bound instead of straight lines

a bound

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Displaying connections between points always same way ignoring bounds
ACTUAL -
Lines goes weird
