Description narcís calvet 2014-11-26 05:12:18 EST 
RadialGradient is centered at the left-top corner of the rectangle instead of the center. Code to reproduce:

void tChart1_AfterDraw(object sender, Steema.TeeChart.Drawing.Graphics3D g)
{
  g.Gradient.Visible = true;
  g.Gradient.Direction = Steema.TeeChart.Drawing.GradientDirection.Radial;
  g.Gradient.StartColor = Color.Red;
  g.Gradient.MiddleColor = Color.Yellow;
  g.Gradient.EndColor = Color.Blue;
  
  Display disp = GetDisplay();
  g.Rectangle(disp.Width / 4, disp.Height / 4, Steema.TeeChart.Utils.Round(disp.Width * 0.75), Steema.TeeChart.Utils.Round(disp.Height * 0.75));
}	  

private Display GetDisplay()
{
  return this.GetSystemService(Android.Content.Context.WindowService).JavaCast<Android.Views.IWindowManager>().DefaultDisplay;
}

This happens both in Xamarin.Android and Android applications with Xamarin.Forms.
