Example 55.6: Controlling Plot Appearance with Graphics Options

This example uses model fit summary statistics from the OUTEST= data set to create a plot for a model selection analysis. Global graphics statements and PLOT statement options are used to control the appearance of the plot.

   goptions ctitle=black   htitle=3.5pct ftitle=swiss
            ctext =magenta htext =3.0pct ftext =swiss
            cback =ligr    border;
   symbol1 v=circle c=red h=1 w=2;
   title1 'Selection=Rsquare';
   title2 'plot Rsquare versus the number of parameters P in '
          'each model';

   proc reg data=fitness;
      model Oxygen=Age Weight RunTime RunPulse RestPulse MaxPulse
            / selection=rsquare noprint;
      plot rsq.*np.
           / aic bic edf gmsep jp np pc sbc sp
             haxis=2 to 7 by 1
             caxis=red cframe=white ctext=blue
             modellab='Full Model' modelht=2.4
             statht=2.4;
   run;

In the GOPTIONS statement,

BORDER: frames the entire display
CBACK=: specifies the background color
CTEXT=: selects the default color for the border and all text, including titles, footnotes, and notes
CTITLE=: specifies the title, footnote, note, and border color
HTEXT=: specifies the height for all text in the display
HTITLE=: specifies the height for the first title line
FTEXT=: selects the default font for all text, including titles, footnotes, notes, the model label and equation, the statistics, the axis labels, the tick values, and the legend
FTITLE=: specifies the first title font

For more information on the GOPTIONS statement and other global graphics statements, refer to SAS/GRAPH Software: Reference.

Output 55.6.1: Controlling Plot Appearance and Plotting OUTEST= Statistics

In Output 55.6.1, note the following:

The PLOT statement option CTEXT= affects all text not controlled by the CTITLE= option in the GOPTIONS statement. Hence, the GOPTIONS statement option CTEXT=MAGENTA has no effect. Therefore, the color of the title is black and all other text is blue.
The area enclosed by the axes and the frame has a white background, while the background outside the plot area is gray.
The MODELHT= option allows the entire model equation to fit on one line.
The STATHT= option allows the statistics in the margin to fit in one column.
The displayed statistics and the fitted model equation refer to the selected model. See the "High Resolution Graphics Plots" section for more information.
