Current and expected behavior

I have a simple line chart with type of x scale set to time and two buttons to set zoom to one and two weeks respectivly for the x-axis.

When zoomScale(...) is called multiple times, some line segments disappears (but the markers are still there). If data are more well behaved (ie. not flucuating to much) I don¨t get the same problem.

Illustrated in gif below.

Reproduction

https://codesandbox.io/p/sandbox/magical-driscoll-l3jzzw?file=%2Fpackage.json%3A1%2C1

chart.js version

v4.3.2

react-chartjs-2 version

5.2.0

Possible solution

The bug (if that is what it is) might well be in chart.js or chartjs-plugin-zoom. I will create a related issue with them also.
