It might help to describe how you created that data set. If possible poste code generated as shown in the log from a point-and-click approach.   If you used a wizard or anything "automated" it is not unlikely that due to the actual content of your data that no numeric (i.e. analysis) variables were created. Some things that can occur in data sources that can cause this are special characters or anything not numeric such as codes like "NA" "N/A" "NULL" or  "MISSING" in a column that should be mostly numeric.   Depending on the actual content of the file there are ways around that but will likely require additional work and possibly actually writing code.   If your "rational" numbers were written in the form of fractions such as 1/2 then that is a non-standard value to read as numeric. Since you say that your "date" also does not appear in the list then that may also have some non-standard appearance as many common date formats would be read by SAS into a numeric variable with a date type format applied. You will almost certainly want the SAS date value to graph properly as most character valued "date" appearances do not sort properly. ... View more
