This section adds an inset to the graph that shows the number of observations used in the regression and the R-square value of the fitted model. You can add an inset by using the DrawInset module that is distributed with SAS/IML Studio. The module is documented in the SAS/IML Studio online Help. The following statements show one choice for creating an inset. Add the following statements at the bottom of the program window, and select → from the main menu.
Labels = {"Num Obs" "R-Square"}; Values = N[2] || NValue2[1]; LabelProps = .; /* accept default settings for labels */ LabelTypeface = "Arial"; /* font */ BackgroundColor = -1; /* no color (transparent) */ Location = 'IRT'; /* Inside, Right, Top */ run DrawInset( FitPlot, Labels, Values, LabelProps, LabelTypeface, BackgroundColor, Location );
Figure 8.2 shows the title, the legend, and the inset created in this chapter.
