Example Using a Grouping Variable
Nonpar Density
Group By
Script
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
points, and the other contour includes 100% of the points.
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.
– you can replace the Group variable.
See “Example Using a Grouping Variable” on page 490.
This menu contains options that are available to all platforms. They enable
you to redo the analysis or save the JSL commands for the analysis to a
window or a file. For more information, see Using JMP.
Example Using a Grouping Variable
This example shows you how to create a scatterplot matrix using a grouping variable.
1. Open the Iris.jmp sample data table.
2. Select Graph > Scatterplot Matrix.
3. Select Sepal length, Sepal width, Petal length, and Petal width and click Y, Columns.
4. Select Species and click Group.
5. Click OK.
