354 Creating Three-Dimensional Scatterplots Chapter 13
Example of a 3D Scatterplot
Launch the Scatterplot 3D Platform
Launch the Scatterplot 3D platform by selecting Graph > Scatterplot 3D.
Figure 13.3 The Scatterplot 3D Launch Window
Table 13.1 Description of the Scatterplot 3D Launch Window
Y, Columns Select the variables to plot on the 3D scatterplot. The order in which you
select the variables determines where the data points appear on the axes:
• The first variable appears on the x axis.
• The second variable appears on the y axis.
• The third variable appears on the z axis.
You can assign the remaining variables interactively through the drop-down
menus below the scatterplot.
Weight
Use the Weight variable to:
• Assign a weight (importance or influence) to the data
• Visualize a fourth variable that sizes the points
Note: Red triangle options account for the Weight variable. If you do not
want this variable accounted for in your analyses, remove it from the launch
window.
When you specify a Weight variable, JMP draws the points as balls. The
balls are scaled so that their volume represents the weight value. You click
and drag the Circle Size slider below the scatterplot to resize the balls.
Freq
Identifies the data table column whose variables assign a frequency to each
row. This option is useful when a frequency is assigned to each row in
summarized data.
