Placing trendline under it series

[????]

Hello, Syncfusion team!

Got one question for you. How to place trendline under it lineseries?

By default it lies over it basic line and overlays it if they match. It spoils ability of segment drag and drop lineseries in points where trendline and lineseries match.

Best regards, Ivan.

Hi Ivan, 

 

Greetings from Syncfusion, we have analyzed your requirement and you can achieve this by extending LineSeries, overriding CreateSegments method then setting ZIndex for line segment visual as per the below code snippet.  

 

Code snippet 

public class CustomLineSeries :LineSeries 

    { 

        public override void CreateSegments() 

        { 

            base.CreateSegments(); 

 

            foreach (var segment in Segments) 

            { 

                Canvas.SetZIndex(segment.GetRenderedVisual(), 100); 

            } 

        } 

    } 

 

           <local:CustomLineSeries XBindingPath="XValue" StrokeThickness="5" 

                              YBindingPath="YValue" ItemsSource="{Binding Data}"> 

                <local:CustomLineSeries.Trendlines> 

                    <chart:Trendline /> 

                </local:CustomLineSeries.Trendlines> 

            </local:CustomLineSeries> 

 

We have prepared a sample based on this, please find the sample from the following location.
