Hi Claudio,
Thanks for using Syncfusion products.
We are able to scroll the chart in Scrollviewer by setting the ManipulationMode as System as shown in the below code snippet.
Code Snippet[Xaml]:
<charts:SfChart ManipulationMode="System">
</charts:SfChart>
Note: If we set the ManipulationMode as System the pinch related zooming will not be work in chart, because the scrollviewer handled the manipulation function.
Please let us know if you need further assistance on this.
Regards,
M.Sheik
