need help about downsampling

[Sharkann]

Hi,

It's a while since I'm trying to find information about how to use the downsampling functions properly.
I have a lot pf series, with more than 100,000 points each, and I need to optimize the display with this kind of function.
I succeeded in attaching a function to a serie, but regarding the different methods (minmax, minmaxfirstlastnul, etc), I did not find any doc on what they are exactly.
Also, talking about the parameters like tolerance, displayedpoints, period, etc...I have difficulties to set them as I don't know what they do.

Is there a clear updated documentation somewhere on how to use this ? On all features, it's not clear.

Thanks a lot !
Regards

Hello!

There's a useful sample you can run to see how to use the Downsampling function:

This sample is in our TeeChart-NET-Pro-Samples repo on GitHub, and the sample in question can be found:

1. for net6.0 under NetDemoNET60
2. for net40 under Feature Demo

Hello,

How do you get the screen shot you posted ?
This is exactly the kind of help i am looking for.

I took the screen-shot having run the samples I mentioned in my last post. That is, clone (or download) the repo, navigate to one of the two folders I mentioned and then open the Visual Studio solution file (*.sln) within it.
