It's really easy to add a trendline to an Excel chart. It would be great if we could do the same with FileMaker.
Some features benefit from the extra thought required by a more difficult implementation. I think trend lines fall in this category. It's super easy to get the wrong idea from a careless trend line; and users with a more nuanced understanding will often want something different than what a catchall trend line feature could achieve. I'd like to see features added to charts that allow us to add things like trend lines ourselves, but I'd prefer if FileMaker didn't do much of the math itself.
I never got happy with FM-Charts so I prefer to use WebViewer and JS instead.
