[Moo] Passing in values to a class

[Dial]

Is it better to pass in values as an option or a static variable?  I
want to be able to send in an array of arrays or a hash of arrays for
plotting graphs.  Most if the graph plugins I have seen parse a table
of data already on the page.  Most of my data is time based and all I
want to do is line graphing.  Like current users on during a specific
time plotted over a 24 hour period.  Just want some opinions.
