Visual Six Sigma: Making Data Analysis Lean

3.2. Visual Displays and Analyses Featured in the Case Studies

The visual displays and analyses that are featured in the case studies represent many different menu items in JMP. In this section, we will give a quick overview of the more basic items and where they can be found.

3.2.1. Graph

Techniques that have visual displays as their primary goal are available from the Graph menu shown earlier in Exhibit 3.6. Many of these displays allow you to view patterns in the data in three or more dimensions. The Bubble Plot is animated, giving one way for you to see behavior over time. In the case studies, we will see examples of the following:

• Graph Builder allows highly interactive simultaneous visualization of multiple variables using a wide variety of graphical elements.

• Scatterplot 3D gives a three-dimensional data view.

• Bubble Plot is a dynamic extension of a scatterplot that is capable of showing up to five dimensions (using x position, y position, size, color, and time).

• Tree Map is a two-dimensional version of a bar graph that allows visualization of variables with many levels.

• Scatterplot Matrix gives a matrix of scatterplots.

• Diagram is used to create cause-and-effect diagrams.

• Control Chart constructs a variety of control charts that, in particular, allow for phases.

• Variability/Gauge Chart is useful for measurement system analysis and for displaying data across the levels of multiple categorical variables, especially when the focus is on displaying the variation within and between ...
