[Live graph] Errors such as noise in the live graph

[SAOKIM99]

When I use the live graph with the value Double, the phenomenon like the video occurs.
The initial signal will fill until full (100 point limit), at which point the graph displays normally.
When it's full, the item is deformed and noisy.

I modified the word /line_chart_sample10.dart and replaced it with this code:
sinPoints.add(FlSpot(xValue, random.nextDouble()));
cosPoints.add(FlSpot(xValue, random.nextDouble()));

Hope to get support soon.

I do have a project that worked fine with fl_charts 0.55.2 and flutter 3.16.0 (dart 3.2.0).
(Note: amplitude changes are due to auto scaling.)

Now I am using fl_charts 0.66.2 and flutter 3.22.2 (dart 3.4.3) and see the same junky graph.

@imaNNeo After some testing I found the problem is introduced in fl_charts version 0.63.0.
Edit 2: I tried using random values as @SAOKIM99 did, while trying any of the here mentioned versions of fl_charts and flutter, and all show noise behavior.

See how the graph changes when I stop the scrolling for a moment:

Edit 1: I just tried flutter 3.22.2 with fl_chart 0.62.0 (only needed to replace MediaQuery.boldTextOverride with MediaQuery.boldTextOf) but I see the same noises behavior.
