Any reason why the slice center points are not stopping in the center of the pie chart?

The values for the middle one are these by the way

pieData.Data.Add(new GraphData() { Value = 81, Color = Color.FromHex("#B9C4D8") });
pieData.Data.Add(new GraphData() { Value = 1, Color = Color.FromHex("#1D386D") });
pieData.Data.Add(new GraphData() { Value = 10, Color = Color.FromHex("#F5A623") });
pieData.Data.Add(new GraphData() { Value = 5, Color = Color.FromHex("#BBC3D3") });
pieData.Data.Add(new GraphData() { Value = 3, Color = Color.FromHex("#1D386D") });

Hello Bank Van Breda,

I would like inform you that the Pen problems is added in Teechart Xamarin.iOS Bugzilla tracker to review the problem to upcoming maintenance release. Here's the link: http://bugs.teechart.net/show_bug.cgi?id=2033

On the other hand, finally, we have found a good solution, that allow to explode any pie slice. The code below show you how can do it:

Code: Select all

		public MainPage()
		{
			InitializeComponent();

			tChart1 = new ChartView();
			tChart1.Chart.Panning.Allow = ScrollModes.None;
			tChart1.Chart.Panel.Gradient.Visible = false;
			tChart1.Chart.Panel.Color = Color.White;

			tChart1.Chart.Walls.Back.Visible = false;
			tChart1.Chart.Header.Visible = false;
			tChart1.Chart.Legend.Visible = false;
			tChart1.Chart.Aspect.View3D = false;
			
			Steema.TeeChart.Styles.Pie pie1 = new Steema.TeeChart.Styles.Pie(tChart1.Chart);
			pie1.Add(81, Color.FromHex("#B9C4D8"));
			pie1.Add(1, Color.FromHex("#1D386D"));
			pie1.Add(10, Color.FromHex("#F5A623"));
			pie1.Add(5, Color.FromHex("#BBC3D3"));
			pie1.Add(3, Color.FromHex("#BBC3D3"));
							
			pie1.Marks.Visible = false;
			pie1.AutoPenColor = false;
			pie1.Pen.Visible = false;
			pie1.Circled = true;

			pie1.ExplodedSlice[0] = 5;
			pie1.ExplodedSlice[1] = 10;
			pie1.ExplodedSlice[2] = 5;
			pie1.ExplodedSlice[3] = 15;
			pie1.ExplodedSlice[4] = 5;

			tChart1.WidthRequest = 650;
			tChart1.HeightRequest = 350;

			Content = new StackLayout
			{
				Children =
									{
										tChart1
									},
				VerticalOptions = LayoutOptions.CenterAndExpand,
				HorizontalOptions = LayoutOptions.CenterAndExpand,
			};

		}
Hoping this helps you.

Thanks in advance

I guess I'll wait for the bug fix... because setting each slice as exploded with value 5 has following visual effect.
