Re: RSI (Relative Strenghth Index) formula calculation

Attached latest excel with TeeChart calculations in green, with the equivalent calculation in dark green. As you can see, the difference is in the calculation of the averages.

Re: WPF Colorline drawing priority

Hello Branislav, Unfortunately the Drawbehind is non-functional in WPF as the tool uses an AdornerLayer to do its drawing, and this layer is always drawn before all others. However, this behaviour can be overridden using a very simple derivative of the ColorLine class, e.g. public class MyColorLine ...

You will note that at runtime the code works correctly, e.g. HorizBar bar; private void InitializeChart() { bar = new HorizBar(tChart1.Chart); bar.Add(50, 0, "f...
