The Scatterplot 3D Report

To produce the 3D scatterplot shown in Example of Information Displayed on the Scatterplot 3D Report, follow the instructions in Example of a 3D Scatterplot.

The Scatterplot 3D report shows a three-dimensional spinnable view of your data. See Example of Information Displayed on the Scatterplot 3D Report. In the launch window, you select the variables and then create the report. The variables are displayed on the 3D scatterplots’ x, y, and z axes. Up to three variables can be displayed at a time.

Note: Any rows that are excluded in the data table are also hidden in the 3D scatterplot.

Description of the Scatterplot 3D Report
Plot source	The plot source box indicates the source of the data in the plot.
Circle Size slider	Note: The Circle Size slider appears only if you have specified a Weight variable. Click and drag the Circle Size slider to resize the balls while maintaining their relative sizes.
Axis controls	Select which variable appears on each axis. Choose the Other option to add a new variable.
Next Axis Set	Cycles through the axis controls for any hidden variables. See Change Variables on the Axes. Note: The Next Axis Set button appears only if your analysis contains more than three variables.

After you create a 3D scatterplot, you can add features such as displaying ellipses around specific data points, showing separate principal components, rotating components, connecting points, and more. See Scatterplot 3D Platform Options for details.

You can also assign colors and symbols (or markers) to data points either on the 3D scatterplot itself or in the associated data table. See Assign Colors and Markers to Data Points and Assign Colors and Markers in the Data Table.

Spin the 3D Scatterplot

You spin the 3D scatterplot report in four ways:

•	Click and drag an empty area on the 3D scatterplot. The 3D scatterplot spins in the direction you dragged the mouse.

Note: Click and drag on an empty area on the 3D scatterplot, not on an axis or data point. Dragging the axis rescales the axis. Dragging a data point only selects the point.

•	Slide the mouse wheel. The 3D scatterplot spins up and down only.

•	Hold down an arrow key. (Before using an arrow on the number keypad, verify that NUM LOCK is turned off.)

•	Hold down ESC. The 3D scatterplot spins left and right only.

In each case, the 3D scatterplot spins as long as you hold down the mouse button, arrow key, or ESC key. The spinning also continues as you slide the mouse wheel.

You can also spin the 3D scatterplot continuously as follows:

•	Click and drag: Hold down SHIFT, click and drag an empty area on the plot, and release SHIFT. The faster you drag the mouse, the faster the 3D scatterplot spins.

•	Mouse wheel: Hold down SHIFT, slide the wheel, and release the wheel. The 3D scatterplot spins up and down only.

•	Arrow keys: Hold down SHIFT, press the arrow key, and release SHIFT.

•	ESC key: Hold down SHIFT and press ESC. The 3D scatterplot spins left and right only.

In addition to automatically spinning the plot, you can oscillate the plot. Hold down SHIFT and CTRL and then click and drag the plot. The plot shakes up and down or left to right, depending on the direction in which you dragged the plot.

To stop the spinning or oscillating, click on the plot or press ESC.

Change Variables on the Axes

The variables on each axis are determined by the order in which you select the variables in the launch window. For example, the first variable that you select is displayed on the x axis. The second variable is displayed on the y axis, and the third variable is displayed on the z axis.

After you create a 3D scatterplot, you can change the variable assigned to an axis, plot a different set of variables, or sequence through all combinations of the variables.

1.	To change the variable on a specific axis, select the axis control drop-down menu and select a different variable.

2.	To add a different variable, click an axis control drop-down menu, select Other, select the variable, and then click OK.

3.	To sequence through combinations of all variables, click the Next Axis Set button until the variables that you want to plot are displayed.

Adjust the Axes

You can manually move or rescale the axis coordinates by clicking and dragging the axis. This option shows a different set of coordinates on the 3D scatterplot. It also lets you change the space displayed between the coordinates (or the coordinate scaling).

You can also specify axis properties by double-clicking the axis and modifying settings in the specifications window.

To Move the Coordinates on the Axis

1.	Place your cursor over the middle of the axis.

2.	Click and drag the axis.

To Modify Coordinate Scaling

1.	Place your cursor over the end of the axis.

2.	Click and drag the axis.

To Rescale an Axis Precisely

1.	Place your cursor over the middle of the axis (the axis, not the label).

2.	Double-click the axis.

3.	Change the minimum and maximum coordinate values.

For more details about updating axes, see Using JMP.

Assign Colors and Markers to Data Points

Each point in the 3D scatterplot corresponds to a row in the associated data table. To highlight points on the 3D scatterplot, you assign colors and markers to the points. The colors and markers are then displayed on the 3D scatterplot and in the data table.

When you click a point, the following items are selected:

•	the point in the 3D scatterplot

•	the corresponding row in the associated data table

•	the point in any other opened graphs, if applicable

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) only highlights them for the current open graphs.

See the Using JMP book 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.
