Found a workaround and it works on both platforms...

change Line.Add( point.Date, point.Value, point.Label, color ); to Line.Add( Utils.DateTime( point.Date ), point.Value, point.Label, color );

Steema.TeeChart.NET.Xamarin.Forms v4.2022.12.20 breaks in iOS v17.0.3

Most values are not rendered correctly and it worked in iOS v17.0.2. The Y values change when rendered but are actually the correct values when inserted into the DataLine.

Then you should probably Obsolete it, so it doesn't cause confusion, as I never found that ANYWHERE in the docs.

Hello, ok great. Looking at your code, as you have created your custom annotation class , I do not see incorrectly to way that draw method has to be called. Let me look more carefully, but it looks good to me. This is a workaround until it is fixed. NOT THE FIX. It should render without having to d...

Hello, **System.InvalidCastException:** 'Specified cast is not valid.' Yes, you're correct, it was a bug which we've already fixed it. We've just upload a new nuget version that includes the fix. Also, the previous exceptions still over on page creation. About this page problem I cannot reproduce t...

With Xamarin.Forms v4.8.0.1821 and Steema.TeeChart.NET.Xamarin.Forms v4.2021.2.25, pinch to zoom don't work on iOS.

I got it to render, albeit incorrectly, by subclassing it and invoking the draw call to it. The DrawText method is NOT being called otherwise, for whatever reason. Edit: AutoSize was being changed for some reason, somewhere. The sizing is ok. This is a workaround: public class AnnotationTool : Annot...

Yes, I do that to find the target point. If you notice, the arrow points to the selected point. The issue is the annotation; It is not being rendered at all. I tried to center it regardless of what point is chosen. public static class ChartExtensions { public static double GetLocalMaximum( this Line...

AnnotationTool = new Annotation(Chart1) { Active = true, Position = AnnotationPositions.Custom, Text = ViewModel.SelectedItemDescription, AutoSize = true, TextAlign = TextAlignment.Start, AllowEdit = false }; // ... } // AnnotationTool.CoerceVisible...

This occurs on both android and iOS.

Annotation Tool Popup doesn't respect placements. Width and Height are both zero, but the bounds show correct sizing. It always renders off the screen, no matter what placement ( left ( x ), top ( y ) ) I set it to. What is displayed: Current settings with the above view: Previous possible related i...

Also, the previous exceptions still over on page creation.
