I have a simple data set of approximately 100 pairs of floating point values. The Calc program reads these data and plots it as an X-Y scatter plot correctly.
I want to test some different functions and get the idea from the Help that this is possible. However, when I try to insert a Trend line, from the insert menu that feature is greyed out.
I am using Windows 8.1 with LibreOffice 4.2.5.2 I am probably misintrepting the help information on this feature, so is there some step that is implied but not explicit?
Thanks for any help.
