Hi Yen,
Thanks for using Syncfusion products.
We were unable to reproduce the reported issue at our end. However, we suspect you have removed the
Syncfusion.SfChart.XForms.Android and
Syncfusion.SfChart.XForms.iOS assemblies in the Android and iOS project respectively which leads to empty chart. So, please ensure the following highlighted SfChart assemblies are referred in your application.
Release notes: https://help.syncfusion.com/xamarin/release-notes/v15.3.0.26?type=all#breaking-changes UG: https://help.syncfusion.com/xamarin/introduction/control-dependencies Note: Clean and Rebuild the projects after remove the assemblies.
If you still facing the issue at your end, please update us more information about chart related code snippet to reproduce the issue which will be helpful for providing further assistance on this.
Regards,
Parthiban S
