In the description of trendlines you can read: ”Unlike linear trendlines, there are several different ways to compute exponential trendlines. We provide only one method right now, but will support more in the future, and so it's possible that the name or behavior of the current exponential trendline will change.” (https://developers.google.com/chart/interactive/docs/gallery/trendlines ).
This text has been there for quite a while and I really would like to know the timeframe for when “more” is coming? I am also very interested in getting a function that retrieves the R2 value. I now use the trendline functionality in forecast calculations and think the trendline finctionallity is awesome and would be so even more if more functionality is added to it. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
