Class
    Foam::coordSetWriters::xmgraceWriter
 
Description
    Write coordSet(s) in xmgrace format
 
    The formatOptions for xmgrace:
    \table
        Property    | Description                       | Required | Default
        buffer      | Use buffered output               | no  | true
        compression | Use file compression              | no  | false
        precision   | Write precision in ascii          | no  | same as IOstream
    \endtable
 
    When called with a single coordSet, will combine all output fields
    into a single file. Although it is nominally 'buffered', it actually
    just keeps track of the number of fields written into the file.
 
    When called as a track writer (eg, with multiple coordSets),
    will emit one file per field.
 
    \section Output file locations
 
    The \c rootdir normally corresponds to something like
    \c postProcessing/<name>
 
    \subsection Geometry and Fields
    \verbatim
    rootdir
    `-- timeName
        `-- setName.{agr}
    \endverbatim
