CALL EXECUTE and graphs
Shafi Chowdhury, Daniel Boisvert · 2001
ABSTRACT “Please change this so treatment groups have the same symbol in the different plots” is a common phrase from statisticians reviewing plots. We then go away, look at what treatment groups there are, which ones are missing from a particular plot, and proceed to change all our SYMBOL statements for the various plots. We repeat this process for each new study. This paper will show how we can solve this problem by creating SYMBOL statements dynamically using CALL EXECUTE. It will show how the programs can always assign the same symbols for each treatment groups regardless of whether all treatment groups are present or not in the plot.
