Chapter 13 Creating Three-Dimensional Scatterplots 357
The Scatterplot 3D Report
• 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.
