@nebulagirl Yes - we actually created https://t.co/JKkKw6Aemv because many users were visiting https://t.co/dxKNwwAAIG to get curve-fitting functionality even though https://t.co/dxKNwwAAIG was designed for bio-assays. Therefore, we thought a general curve-fitting solution would be useful.
@JulesGari@JulesGari - thank you for reporting this. We've had some scaling issues impacting a small number of users. This was caused by unexpected increased demand. We've added more scaling capability now so this should have been resolved.
@emnode@ryanstruyk@bethlevin Don't forget that you can use the Swap button on the right so you can compute x values from y. Also, you can use Share to create a link to share your data and fit.
@akaplin These values are not actually coefficients but information about how the spline was smoothed. The reported values are:
S = Smoothing Factor
I = Iterations
IP = Inflection Points

@NitramAdams Thank you for your kind feedback! Do you mean that you would like to change the plotted x axis range? One way to do this currently (depending on the fit method) is to press Predict (so x is left column) then enter an x value outside currrent range.

@davi_d_omjan Thanks for your expressive feedback. Please be fair though, we don't state anywhere that "it's all free" . In fact, we make it very clear what is free and what is part of the subscription service on the "More info" link. Also, the free membership provides ongoing free fits.
