--- Comment #8 from Eduardo <eduponto...@gmail.com> --- Hi people, thanks to the comments (In reply to disuser from comment #2) > I have just checked it with the data you provided: > > x: (0; 0,37; 0,5) > y: (0; 20; 25) > > There are two variables (columns) of Numeric type (x, y) with three cases > (rows) each.

Should i change the status to resolved? -- You are receiving this mail because: You are watching all bug changes.
