Measurement Level (GGRAPH command)

You can change a variable's measurement level temporarily by appending the qualifier [LEVEL=measurement level] to the name in the variable specification. (The variable's measurement level in the dictionary is unaffected.) Valid values for the measurement level are SCALE, NOMINAL, and ORDINAL. Currently, the measurement level qualifier is used to influence the behavior of the REPORTMISSING keyword. If the measurement level is set to SCALE, missing values are not reported for that variable, even if the value of the REPORTMISSING keyword is YES. If you are using the NAME qualifier for the same variable, both qualifiers are enclosed in the same pair of square brackets. For example:

GGRAPH 
  /GRAPHDATASET NAME="graphdataset" VARIABLES=jobcat[NAME="empcat" LEVEL=NOMINAL] COUNT()
  /GRAPHSPEC SOURCE=GPLFILE("simplebarchart.gpl").
