Line breaks in the line legend

Problem:

How can I add line breaks into the line legend labels?

Solution:

If you define the line mapping name as the variable or zone name, add \n to the variable or zone name (defined in Data > Data Set Info) at the desired location of the line break.  If you are using a static Map Name defined directly in the Mapping Style dialog, add \\n  at the desired location of the line break.
