Polynomial Trendline for a Line Chart

[rmcgrath]

Hello - I'm looking for a work around for this issue, as Power BI only offers a linear trendline.  Does anyone have a solution?  DAX? R? Python?  I have a line chart that I would like to show a polynomial trendline because of all the peaks and valleys - a linear trendline is pretty useless.

Surely there has to be a way to write some DAX for this? (Or R or Python?)

Yes, an R or Python visual could work. Note that you would lose interactivity.

An alternative would be Deneb, as @KerKol suggests here Re: Creating Polynomial Trend Lines in PowerBI Cha... - Microsoft Fabric Community
