Gplot
symbol color=blue value=square interpol=none;
proc gplot data=work.australia ;
plot lifesat*lngdp /grid;
run ;
The symbol statement defines the color, the value and the interpolation between the points on the plot.
interpol can be "none" (scatterplot), "needle", "regression" (regression line), "line", "spline".
You can put two plots on the same graph with the 'overlay' option in the plot statement
symbol1 color=blue value=square interpol=none;
symbol2 color=red value=dot interpol=line;
proc gplot data = australia2 ;
plot lifesat*lngdp = 1 lifesat_pred*lngdp = 2 /overlay grid;
run ;
Export to other format
You can export to png, jpeg, pdf … Here is an example with a png file.
goptions reset=all;
filename output "W:/…/regression.png";
goptions device=png gsfname=output gsfmode=replace;
symbol1 color=blue value=square interpol=none;
symbol2 color=red value=circle interpol=line;
title "Regression Line" ;
proc gplot data = australia2 ;
plot lifesat*lngdp = 1 lifesat_pred*lngdp = 2 /overlay grid;
run ;
