Steema.TeeChart.Tools.NearestPoint Change event doesn't trigger

Steema.TeeChart.Tools.NearestPoint Change event doesn't trigger because the kind parameter is never MouseEventKinds.Move . I clicked and dragged on the chart but it never triggered. Only the down and up events fired. protected internal override void MouseEvent( MouseEventKinds kind, MouseEventArgs e...

Annotations are broken. Can't draw on the canvas.

Steema.TeeChart.NET.MAUI v6.2024.8.29 Seems that the following is the culprit: Microsoft.Maui.Graphics.Platform.PlatformCanvas Seems like the CurrentState is null. It should be an instance of PlatformCanvasState . public override void FillRectangle(float x, float y, float width, float height) { var ...

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

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.

Re: Pan/Zoom and Screen Tap is broken on iOS.

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

Re: Annotations do not render. Steema.TeeChart.NET.Xamarin.Forms v4.2021.2.25

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...

Re: Annotation Tool Popup doesn't respect placements.

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...

Re: Annotation Tool Popup doesn't respect placements.

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...
