Hi p1gd0g,

We have replicated the reported issue "Trackball is not updating properly for bubble series with empty points in combination with other type series". We will fix and include the changes in our weekly patch release which is expected to be rolled out on January 7, 2025. We will notify you here once the release has been rolled out, and we appreciate your patience in the meantime.

Root cause: Empty points calculation is not correct for bubble series when it’s combined with other series types.

Regards,
Aswini S.

Hi @p1gd0g,

The reported issue has been fixed and rolled out in our weekly patch release on January 7, 2025. So, we kindly request you to upgrade the syncfusion_flutter_charts package to the latest version as below.

Version: https://pub.dev/packages/syncfusion_flutter_charts/versions/28.1.38

Root cause: Rounding x-values in DatetimeCategoryAxis to find the nearest point index, similar to CategoryAxis with arrangeByIndex, causes the trackball to incorrectly display the next index when multiple series are used.

Regards,
Aswini S.
