Hi,

i need to create a scatter plot with a best fit curve (Polynomial 2nd order), like the example on this link:

https://chart-studio.plot.ly/create/?fid=mariahh:94#/

(This is a 4th order, but no problem i’m interesting to know the concept.

I have found a lot of example in the Plotly chart studio like the one above, but my problem is how to generate the trace or the parameters estimates (A, B, C), starting from my scatter dataseries.

Is it possibile directy in Plotly.js or i need an external library to calculate the values of the best fit curve and pass it to Plotly.js?

Thanks to anyone who wants to help me.
