Question about usage : how to force the curve to go through (0,0)

[ChinaFred]

Hello
We have to perform a polynomial regression of order 2 : Ax² + Bx + C
we want to force C to be 0
How can we perform this operation ?

NB this option is available in excel

Best regards

Hello @ChinaFred, at this moment this option doesn't exist in our package, but it is a good idea, if you are interested in implementing it we'll be happy to help you.

It seems that the current code is actually capable of this calculation, just passing an array to the degree field.

In this specific case, for example, it would be [1,2], or [2,1], omitting 0.
