You know... maybe ...
a.) In Excel you can Show a function y=f(x) easily, based on a table x,y.
b.) You can also select then for a function "smooth lines".
Everything ok so far and Excel does really Show a nice "smoothed" graph which seems to contains all the original Points of my "non smooth" value table.
Does anybody has an idea how Excel does calculate the "smooth" function?
I googled, but missed the relevant Information until now.
Thanks in advance.

If only there was a C# library for each of those curve-fitting methods

Yes true, and thanks for blaming me. I find all this also, but _what exactly _ Excel is using?
And in case you think you know everything, than please explain which algo I have to use that my original Points are in the smooth function....
Google I can do by myself, but get the real Background is sometimes more than just a Little bit googling and copy&paste...

Nobody "blamed" you ! If anyone is to blame here, it should be this lazy flea, who didn't go a-googlin' before he oped his yap JustWatchLittle wrote: And in case you think you know everything, than please explain which algo I have to use that my original Points are in the smooth function....
So, we should read your mind, figure out what type of spline function you want ?

You should reread and rethink this post.
It comes off in a pretty bad way, Marc is really trying to be helpful, and there's not enough info in the thread to conclude that he is "blaming" you.

I'm LMAO reading the replies. My reply to Bill was specifically meant for Bill as he was wishing there were some C# implementations. I was actually surprised how little how I found googling around.

Well duh, I wasn't googling for what algo Excel was specifically using, just trying to find if someone, say on github, had done a broad implementation of several algorithms. Never came up with anything, though I imagine in Python/Numpy they exist.

Everything but that.
