Hi.
We're using the SfChart lib extensively in our product and are experiencing serious problems since upgrading to UWP.

The product draws multiple series in a chart. Most of the series rely on double.NaN points and the ShowEmptyPoints set to false in order to present gaps in the lines. When doing this in the UWP lib the client's used memory grows exponential to several hundreds of megabytes and the entire UI freezes. Setting the ShowEmptyPoints to true removes the crash, but this is not an accepted solution for us since it doesn't create gaps between lines (it draws the gaps as zero-value points).

I've created a repo that illustrates the bug. Please find attached zip file.

Can you verify that this is a bug?

Would appreciate an ETA on when you think this will be fixed. This is problem is holding back our release.

The SfDataGrid (which is not available yet) and the SfChart components are the sole reason for using Syncfusion library.

Regards,
Gustav
