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

ya..i know that method. But, is that possible for not using that "tools". I just want to plot a trend line by a click in get my question?

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.
