The Scatterplot Matrix red triangle menu provides the following options:
Show Points
Shows or hides the points in the scatterplots.
Points Jittered
Turns the jittering of the points in the scatterplot on or off. This option is available when at least one variable is either ordinal or nominal.
Fit Line
Fits a simple regression line and its mean confidence interval to the scatterplots.
Density Ellipses
Shows or hides the outline and area of the density ellipses. See Example Using a Grouping Variable.
Shaded Ellipses
Colors the area within each ellipse. See Example Using a Grouping Variable.
Ellipses Coverage
Enables you to select an α-level for the ellipses to cover.
Ellipses Transparency
Enables you to select the transparency of the shaded ellipses, where 0 is completely transparent and 1 is completely opaque.
Ellipses Color
Enables you to select a color for the outline and the area within an ellipse.
Nonpar Density
Shows or hides the nonparametric density, which represents the areas where the data points are the most dense. The nonparametric density estimation is helpful when you have a lot of points and the density of the points is difficult to see.
There are two quantile density contours. One contour includes 50% of the smoothed density, and the other contour includes 90% of the smoothed density. Since the percentage is based on the smoothed density, the percentage may not agree with the actual proportion of points within a contour.
Group By
In the Group By window, you can perform the following actions:
– If you did not select a Group variable in the launch window, you can add one now.
– If you did select a Group variable in the launch window, you can remove the existing Group variable, or you can replace the Group variable.
See Example Using a Grouping Variable.
Lock Scales
Prevents axis scales and gradient legend scales from automatically adjusting in response to data or filtering changes.
See Local Data Filter, Redo Menus, and Save Script Menus in Using JMP for more information about the following options:
Local Data Filter
Shows or hides the local data filter that enables you to filter the data used in a specific report.
Redo
Contains options that enable you to repeat or relaunch the analysis. In platforms that support the feature, the Automatic Recalc option immediately reflects the changes that you make to the data table in the corresponding report window.
Save Script
Contains options that enable you to save a script that reproduces the report to several destinations.
Save By-Group Script
Contains options that enable you to save a script that reproduces the platform report for all levels of a By variable to several destinations. Available only when a By variable is specified in the launch window.
