Scatterplot 3D Platform Options
To select one point, click the point.
To select several points, double-click the 3D scatterplot and drag the cursor over the points. A box is
displayed to indicate which points are selected.
To deselect points, double-click the 3D scatterplot.
To assign a color or marker to selected data points, proceed as follows:
1. To assign a color to the selected point, select Rows > Colors and then select the color.
2. To assign a marker to the selected point, select Rows > Markers and then select the marker.
Assign Colors and Markers in the Data Table
You can assign colors and markers to rows in the data table. The colors and markers appear next to the row
number in the data table and on the 3D scatterplot. This option distinguishes points for each variable, and
you can save the settings in the data table. Assigning colors and markers to specific data points (as described
in “Assign Colors and Markers to Data Points” on page 358) only highlights them for the current open
graphs.
See Using JMP for details about assigning colors and markers in the data table. For details about changing
the size, quality, or transparency of markers, see “Scatterplot 3D Settings” on page 365.
Scatterplot 3D Platform Options
The red triangle menu next to Scatterplot 3D contains options to customize the display and to compute,
rotate, and save principal or rotated components.

Shows or hides the data points on the graph.
Shows or hides the source and axis controls displayed beneath the 3D
scatterplot. See Figure 13.4.
Draws lines from each point to the plane created by the x and z variables that
you selected on the launch window.
Connects the points with a line. Points can be connected on the data as a
whole or in groups. You can also group data by a specific variable.
Draws one or more normal contour ellipsoids, that is, three-dimensional
ellipses that encompass a specified portion of points. You specify whether
you want an ellipsoid for all of the data or for each group. You can also
control the size and transparency of the ellipsoids. For details, see “Normal
Contour Ellipsoids” on page 361.
