Making graph through points

Hi. I have been trying to connect the points to make a graph. And I had tried on the suggestions that people gave under the questions similar to mine, like the Polynomial[list1] and FitPoly functions. Yet my graph turned out weird. So could anyone help me with this problem?

Hi

ik made a copy of the included picture and worked on it with the command FitPoly({C, D, E, F, G, H, I, J, K, L, M, N}, n), where n is a slider.

Even with n=4 I get a reasonable good result.

Point is: if you want a function that passes exatly through all the points, then the function you found isn't weird at all. If you want a best fit function, than you're better of with Fitpoly

I think I get you. But I'm curious that why do you need the n as a slider?

You don't need a slider at all, you could as well type a number directly. But there's a reasonable chance that the number you typed isn't the best choice you can make. If you use a slider you can easily compare different options.

With three points of course you type 3 without slider. With some 10 points I like to compare different solutions.

And regarding the saving of the picture: I just used a screen capture program to make a picture of the graphic view tu adjust it with the axes of the new file
