Desmos sin wave sum shows different to code

Question

I have followed The Coding Train's Discrete Fourier Transformation series, and added a feature which spits out the coefficients of the equation.

I wrote test in the program, which looked nice. However, when I plugged in the coefficients into Desmos, these were the results (all attempts were messy):

Program:

Desmos:

I believe the error is related to the function in desmos / wrong data shift, however I am unable to fix this. The data seems to be lining up in similar spaces in all of my attempts.

Q & A:

• The data from the program seems to be correct
• The data is not heavily modified from the original program, as it is clearly not the issue
• The data is transferred to desmos simply by copying and pasting the results from the console
• The desmos formula can be found in the top left of the image

EDIT:

If there is another way of generating the circles so that this may work, please feel free to respond. Any help whatsoever is always appreciated.
