Topic: Insert Function

I used to use GRAPH on Windows but now tried to use GRAPH on MAC.  I've downloaded the software and tried to do the same thing, nothing seems to work. 
I import the data series but when I try to fit a function to it, nothing happen.
Did I miss something?  Please help

Re: Insert Function

I just tried importing a point series and created a trendline from it without any problems on a Mac. It looks like I need more information to reproduce it. Can you for example attach the data series you are importing?
