Join Dots
If you turn this option on, the stat tool will join the dots in the same order as they are listed in the table. This usually just produces a "bird's nest" - especially if the data is unsorted.
Unsorted Data Sorted by x Values
You can use this feature, providing you enter the points in a logical order, to construct just about any diagram you wish.
Regression Model
The regression model allows you to select which of the seven regression models the stat tool uses to calculate the regression line and residuals.
