Example 4: Generating a Scatter Plot

Features:

SCATTER statement

SCATTER statement options:: COLOR=; SIZE=

This scatter plot examines the results of measuring the petal length, petal width, and sepal length for the flowers of three species of irises. The Scatter statement in this example relies on the procedure defaults to scale the axes to include all the data values, label the axes with the variable's labels, divide the axes into three even intervals, rotate the horizontal plane 70 degrees around the vertical axis, tilt the plot 70 degrees toward you, and display the plot with the default ODS style.

Program

goptions reset=all border;

title1 "Iris Species Classification";
title2 "Physical Measurement";
title3 "Source: Fisher (1936) Iris Data";
footnote1 j=r "Sepal Width not Shown";

proc g3d data=sashelp.iris;
  scatter PetalLength*PetalWidth=SepalLength /
     color="light blue"
     size=1.5;

Program Description

Set the graphics environment.

goptions reset=all border;

Define the titles and footnote.

title1 "Iris Species Classification";
title2 "Physical Measurement";
title3 "Source: Fisher (1936) Iris Data";
footnote1 j=r "Sepal Width not Shown";

Generate the surface plot. Set the marker color to light blue and the marker size to 1.5 cells.

proc g3d data=sashelp.iris;
  scatter PetalLength*PetalWidth=SepalLength /
     color="light blue"
     size=1.5;

run;
quit;
