LightningChart Support Forums

When using AreaSeries, setting LineVisible = true allows the DrawColumnForArea array to be regularly cleared from memory, whereas in the fault state (LineVisible = false) the memory used by DrawColumnForArea keeps increasing forever.

Here is how you can confirm this: In the ExampleAreaSeriesRealTimeXY example window, LineVisible is normally set to true and memory gets recycled, but if you change that boolean to false, the memory that DemoAppWpf.exe is using keeps increasing over time.

Thanks,

Hello,

Thank you for reporting this issue.
You are correct, as this does cause a memory leak. We have also detected similar issues earlier with HighLowSeries. Therefore this particular issue is fixed in our next release, in which the focus is on bug fixes. This patch is actually estimated to be released next week, so after that simply updating LightningChart should solve the issue.

Thank you for looking at this for us. We look forward to the next release.

The issue was fixed in the latest (v8.4.2.4001) LightningChart release.
All the best.
