Scattergrams

On the Stats tab, in the Exploratory Data Analysis group: Click Scattergrams to calculate correlation statistics for any variables in a file. Both simple linear (when there is only one X-axis field) and multiple linear (when there is more than one X-axis field) regressions can be calculated and displayed.

Different (exponential, logarithmic, polynomial, power and moving average) regression types are supported whenever there is only one X-field. Optionally, the regression line and its confidence bands may be displayed and colour coded. Confidence bands refer to the confidence of the mean, not the data set.
