Thanks for the celerity with your reply! I must say i was beginning to think that... Instead of using this CustomGridLine is there another control that may be posible to use so it could be sent to the back? I attach a pic of my XAML, i

I created a customGridLine dinamically from source: double[] strokeArr = { 1, 1, 1 }; CustomGridLine c2 = new CustomGridLine(); c2.Value = value; Brush borderBrush = new SolidColorBrush(Color.FromArgb(225, 155, 55, 75)); c2.Stroke = borderBrush; c2.StrokeThickness = 3; c2.StrokeDashArray = new DoubleCollection(strokeArr); chart1.AxisY.CustomGridLines.Add(c2); But my problem is that the CustomGridLine appear over the Points of the chart. I'd like to mive this GridLine backwards downto the bottom of the chart. I tried to create this CustomGridLine before adding all the points to the chart and no way... Thanks AdolfoCG
