How do I add a trend line?
I know I saw this at Domopalooza in one of the breakout sessions (even tried to snap a pic of the screen but wasn't fast enough), so perhaps a Domosapien or a Major Domo with superior math skills can help me figure out how to derive a Beast Mode formula to demonstrate a trend line over a particular metric. What I'd like to do is use a Column + Line card, and have the line be the trend. While the columns may go up and down across the time series, the trend is more than just the net change between the first and last point - there's an overall (weighted?) slope to the result across multiple periods.
How can this be accomlished? Thanks in advance, Community!
