I'm afraid I don't understand your requirement here—could you please be more specific? Please be aware that we have a large, single demo app which showcases most of TeeChart's functionality here (for .NET 6.0) and here (for .NET Framework 4.0)—maybe these examples can help you specify what you're looking for.

In that case, with reference to the two examples I pointed you to in my last post, you should look a the DownSampling function:
