# Set graph settings
#
# Possible settings:
#
# Name:               data_types (required)
# Description:        Array of events from the mimedefang log file to
#                     graph.
# Supported Values:   These event names are not fixed.  If you put an event
#                     in mimedefang-filter with md_log('event'), then you
#                     can use it here.  The values used in the example
#                     mimedefang-filter are 'spam', 'virus',
#                     'suspicious_chars', 'message/partial', 'bad_filename',
#                     'non_rfc822', 'non_multipart'.
#                     'all' is also supported, but it must be listed by itself.
#
# Name:               graph_type (required)
# Description:        Type of graph to output.
# Supported Values:   'line' or 'stacked_bar'
#
# Name:               grouping (required)
# Description:        Which value to graph from the md_log file.
# Supported Values:   'summary', 'value1', 'value2', 'sender', 'recipient'
#                     'subject'.  value1 and value2 are the optional
#                     parameters that can be logged with the md_log command
#                     from mimedefang-filter.
#
# Name:               grouping_times (required)
# Description:        Array of Time intervals to use for grouping
# Supported Values:   'hourly', 'daily', or 'monthly'
#
# Name:               top_n (optional)
# Description:        Limit number of values to the top n.  This
#                     value is recommended when looking at
#                     senders, recipients, or subjects.
#
# Name:               value1_title (optional)
# Description:        Title used in the header if value1 is
#                     graphed.
#
# Name:               value2_title (optional)
# Description:        Title used in the header if value2 is
#                     graphed.
#
# Name:               filter (optional)
# Description:        Regular expression filter that can be
#                     used with value1, value2, sender, 
#                     recipient, and subject
#                     Common uses: 
#                     '@westover.org' to filter sender or recipient by domain
#                     '^(?:(?!klez).)*$' to filter OUT klez in a virusname
#
# Name:	              filter_name (optional)
# Description:        If a filter is used, the filtername will be appended
#                     to the Graph Title as "filtered by $filter_name" and
#                     appended to the end of the filename.
#
# Name:               $GraphSettings{'title'} (optional)
# Description:        Assigns a title for the chart.
