Clustering Separate Variables (GPL)

This example demonstrates how you can cluster separate variables.

Figure 1. GPL for clustering separate variables

SOURCE: s = userSource(id("Employeedata"))
DATA: jobcat = col(source(s), name("jobcat"), unit.category())
DATA: salary = col(source(s), name("salary"))
DATA: salbegin = col(source(s), name("salbegin"))
COORD: rect(cluster(3))
SCALE: linear(dim(2), include(0.0))
GUIDE: axis(dim(2), label("Mean"))
GUIDE: axis(dim(3), label("Job Category"))
ELEMENT: interval(position(summary.mean("Beginning Salary"*salbegin*jobcat)), 
                  color("Beginning Salary"))
ELEMENT: interval(position(summary.mean("Current Salary"*salary*jobcat)),
                  color("Current Salary"))
