      Description

      The y-domain parameter will allow the facet2D function to change the query for the y dimension in a facet2D aggregation:

      Syntax:

      facet2D(stocks, 
              q="ticker_s:jpm", 
              x="yearMonthDay", 
              y="ticker_s", 
              y-domain="*:*", 
              dimensions="50, 50",
              max(change_d)) 

      The example above changes the query for the y-dimension to be

      *:* 

      The main query is still applied to the x-dimension.

      This aggregation behavior creates graph adjacency matrices that can be mined for correlations.
