Serious memory leak using LineSeries

[GuildOfCalamity]

Steps to reproduce

1. Create WinUI3 desktop application.
2. Install OxyPlot.WinUI 0.9.3
3. Create <PlotView> and bind it to a PlotModel containing a LineSeries
4. Run a timer that adds one DataPoint every second.

Platform:
.NET version: 6.0

Expected behaviour

No memory leak.

Actual behaviour

Huge memory leak. Was tested side-by-side using Microcharts, which displayed no memory leak.

Do you happen to have any more details about what exactly is leaking the memory? I'm not quite sure how LineSeries itself could leak, but who knows.
Could it also be something in OxyPlot.WinUI? Did you by any chance also test this with other UI Frameworks?

I'd suspect the WinUI provision in this case (had leaks in other provisions in the past): pinging @HavenDV because I think 0.9.30 must be one of his. Curve is disturbingly super-linear.

@GuildOfCalamity I'm not in a position to test it myself, but if you can provide a minimal reproducing example and if possible work out which objects are filling up all the memory via a profiler that would help with the investigation (e.g. snapshot from perf view)

@Jonarw I haven't had a chance to run a profiler on this. Microcharts seemed to be a good fix for the issue. I will add that in the screen shot you will see a small dip at the very end, that was me clearing the graph object of all DataPoints and you can see that only a very small amount of memory was reclaimed by the GC. Running the same test using Microcharts showed a total memory commit of 159 MB which was to be expected (not 1.9 GB like the OxyPlot). Hopefully this can be addressed in the future because I would like to use OxyPlot.
