This is an object used to create an instance of a plot which shows the coverage of available SuperDARN data.
This is embedded within the app, but using the constructor, you can add a standalone coverage plot independent
of the app. This object is, in effect, a particular implementation of the generic **CataloguePlot** library, 
designed to look like the static plots available on the `VT website <http://vt.superdarn.org/tiki-index.php?page=Data+Inventory>`_.

Prerequisites
=============

The following function libraries are required in order to use this object:

- ``/js/sdcat/SDCat.js``
- ``/js/catalogue-plot/CataloguePlot.js``

Constructor
===========

.. js:class:: SDCat.CoveragePlot(options)

   .. attribute:: options
      :noindex:
   
      (*Object*) - List of options. These options set attributes of the object:

      .. attribute:: sdcat
         :noindex:
   
         (*Object*) - Object containing configuration parameters for the SDCat object. Here, you need to specify
         the URL to the SDCat API instance you wish to query.
   
         Example::
   
            var options = {
               sdcat: {
                  url: "http://localhost:8082/api/v2/"
               },
            };
  
      .. attribute:: plotId
         :noindex:

         (*String*) - ID of the div that will contain the plot. If this is not specified, the plot will be appended to the
         main body of the page. (Default: ``null``).
 
      .. attribute:: radars
         :noindex:
   
         (*Array*) - Array of 3-letter radar codes which belong to the radars that are to be shown on the plot. (Default: ``empty``).
   
      .. attribute:: fileTypes
         :noindex:
    
         (*Array*) - Array of file types that are to be shown on the plot. (Default: ``empty``).
   
      .. attribute:: coverageType
         :noindex:
   
         (*String*) - The coverage type to use on the plot. This is the source of the date information i.e. **File** for dates based on the
         date information in the file name or **Date** for dates based on the date information in the data file itself.
   
      .. attribute:: startDatetime
         :noindex:
   
         (*String*) - ISO formatted date/time string representing the start point of the plot (e.g. **2017-01-01T00:00:00**).
   
      .. attribute:: endDatetime
         :noindex:
   
         (*String*) - ISO formatted date/time string representing the end point of the plot (e.g. **2017-12-31T23:59:59**).
