Title: jqPlot Options

**This document is out of date.  While the options described here should still be 
relavent and valid, it has not been updated for many new options.  Sorry for
this inconvenience.**

This document describes the options available to jqPlot.  These are set with the 
third argument to the $.jqplot('target', data, options) function. Options are 
described using the following convention:

{{{ 
property: default, // notes 
}}}

This document is not complete!  Not all options are shown!  
Further information about the options can be found in the online API 
documentation.  For details on how the options relate to the API documentation,
see the <Options Tutorial> in the optionsTutorial.txt file.
