In GUI after you plot your data, you can drag down "Tools", there is a menu called "Basic Fitting".

Even better, I just want to think about what I want to do, and have the computer know exactly what I intended. Why bother wasting the effort of clicking a mouse? On second thought, why involve me at all? Why not have the computer automatically decide what it is I would have wanted to do, were I actually to do anything, and do it all for me while I sleep?

Some of us prefer code, especially when we need to apply the same code to 10's, if not 100's of files and need the trendlines for all of them. It is very time consuming to have to do that for every file.

I've written a simple function called polyplot to add a linear trend line to plots. Get it on the File Exchange here.
