Wizard Harry Potter makes magic just waving his wand around and shouting out spells. Using SAS Enterprise Guide (and you are welcome to shout out your own commands too) you can create some magic, allowing the Stored Process Wizard to code for you. On Step 2, the "Include code for"
Statistical graphs often include display of derived statistics along with the raw data. Often these statistics are presented in a tabular format inside the graph. With SGPLOT procedure, a table of statistics can be added to the graph as an inset table, as shown below. Using a Stat Table: SGPLOT code:
