Required to load the plot data from a properties file. One plotting option must be selected.

The file must contain a YVALUE property and may optionally contain a URL property. If present, the URL will be opened when the data point on the plot is clicked.

The specification of this file can use wildcards like build/report/*/report.properties but only the first file resolved by the wildcard will be used. See the @includes of Ant fileset for the exact format.

For example, a properties file might look like:

  YVALUE=3.342
  URL=http://foo.bar/
