Reviewing the code
The following table describes the highlighted code and its function:
Code Description
URL="Salary_Details.cfm?
Dept_Name="
When the user clicks a data point, call the
Salary_Details.cfm page in the current directory,
and pass it the parameter named Dept_Name.
The parameter value must come from the
URLColumn attribute.
URLColumn="Dept_Name"
Complete the URL string with the value from the
query Dept_Name field. So, if the Dept_Name is
HR, ColdFusion calls the following URL:
Salary_Details.cfm?Dept_Name=HR
