* Iris1 Example

  The sashelp.iris dataset consists of four variables, 
  all measured in millimeters: PetalLength, PetalWidth, 
  SepalLength, SepalWidth. Change the plot 
  statement in gplot or the scatterplot statement 
  to create all six pairwise plots
  Use gplot to plot SepalLength vs. SepalWidth;

data newiris;
   set sashelp.iris;
   if species='Setosa' then symbol=1;
   else if species='Versicolor' then symbol=2;
   else symbol=3;

goptions reset=symbol;

symbol1 v=star h=1.5 c=black;
symbol2 v=triangle h=1.5 c=black;
symbol3 v=+ h=1.5 c=black;
proc gplot data=newiris;
   title 'Fisher Iris Data -- 1936';
   plot SepalLength*SepalWidth=symbol;
