How to plot a set of unique coordinates on a map

[ballardw]

Basic approach is to use If/Then statements in a data step to set a desired color /symbol based on the value of such a variable.

Then use  Legend statements to provide description text to match the color /symbol you used.

You could use the value of the 'present' variable to control the color of the dots, such as ...

data coordinates; set coordinates;

length color $12;
xsys='2'; ysys='2'; hsys='3'; when='a';
function='pie'; rotate=360; size=1.0;

 if present=0 then color='red';

 else if present=1 then color='green';
run;
