Enhancing Plots

Specifying SYMBOL Statements

You can specify a single SYMBOL statement to enhance a specific plot line, as shown below . . .

     symbol1 color=red value=star interpol=spline
             height=1 cm width=4;  
     proc gplot data=clinic.totals2000;
        plot therapy*month; 
     run;

Plot with single SYMBOL statement

. . . or you can specify multiple SYMBOL statements to control several plot lines.

     symbol1 color=red value=star interpol=spline
             height=1 cm width=4;  
     symbol2 color=green value=plus interpol=spline  
             height=1 cm width=4; 
     proc gplot data=clinic.totals2000;  
        plot therapy*month treadmill*month / overlay;  
     run;
