SfChart Doesn't render correctly on android

[Jamie holcroft]

I have chart with a Spline Series that is data bound to an observable collection of my model. This collection is updated from events from a Microsoft Band, this renders fine in the universal windows project, but does not update on android to render changes to the collection.

I have attached screenshots and the project.

Hi thank you for replay, i don't understand what mean the binding that you done in sfCarh 

<chart:SplineSeries Label="Series"  ItemsSource="{Binding }" XBindingPath="XValue" YBindingPath="YValue">

Hi Amro,

Thanks for the update.

1. {Binding} - this will work when the binding context is directly set to the property in the ViewModel.

2. {Binding PropertyName} - this will work when the ViewModel object is set as BindingContext and its property is bound to ItemsSource.

We have also attached a sample for this for your reference which can be downloaded from the following location.

Hi Jamie,

Still we were not able to reproduce the reported issue in Galaxy tab A with latest Xamarin.Forms pre-release version. The given sample is working fine in the mentioned tablet device. As per our previous update, please confirm us whether the sample provided in our previous update is working properly in your end. In that sample, click “ADD DATA” button which is placed top of the screen, and ensure that the new data is added at 1st index in Chart.
