Modifying Individual Plots in a Diagnostic Panel

About the Fitness Example

This example analyzes the resting and active pulse rates for participants in a physical fitness study. As part of the study, individuals of various ages and weights run for a variable amount of time, and their pulse rates are measured before and after the run. The code uses the REG procedure to create a graph with paneled diagnostic plots. The running time (RUNTIME) is a response variable in the study.

Modify the Fitness Example

Change the Graph's Title

By default, the graph's title contains the RUNTIME variable. Change the graph's title to make it more meaningful.

Double-click the title (Fit Diagnostics for runtime).
Select all of the text and type the new title Model Fit Diagnostics for Regression Analysis of Running Time.

Change the Axis Label for a Cell

In this example, each cell has its own set of axis labels.

To change an axis label:

Double-click the Y axis label for the middle cell. (The label contains the text runtime.) A box appears around the text.
Change runtime to Run Time with a capital R and T.

Change the Color of a Plot

For the type of graph used in this example, you can modify plot properties separately for each cell.

To change plot properties:

Right-click inside the middle cell and select Plot Properties. The Plot Properties dialog box appears.
On the Plots tab, select lineparm2 from the Plot list box.
Select a blue color from the Color list box.
Click OK. The diagonal plot in the middle cell becomes blue.

Change the Graph's Background Color

To change the graph's background color:

Right-click the graph and select Graph Properties. The Graph Properties dialog box appears.
Select a gray color from the Fill list box.
Click OK.
