A TrendSpec Identifier Value is a string value that is specified without quotation marks, in the format:
<Identifier> = <Identifier value>
Example:
Format = TWENTYFOURHOUR
(for the XAXIS times to use 24-hour clock notation)
For a list of the identifier values that each optional identifier supports, see the tables in the subsections that follow; also see Supported FontStyle Identifier and Integer Values.
Identifier values are case insensitive and cannot include any character spaces.
