How to parse sub collection from mongo?

Hi, everyone, cant found a valide procedure for print the collection in my template,

{ "_id" : "MthCceks4PcgGvwXg", "name" : "buyhistory", "createdAt" : ISODate("2016-04-03T15:56:45.619Z"), "data" : [ { "volume" : [ "1165" ], "avg" : [ "850550154.15" ], "max" : [ "1040300000.01" ], "min" : [ "1500000.00" ], "stddev" : [ "431669123.56" ], "median" : [ "1010980001.00" ], "percentile" : [ "1040293080.98" ] } ] }

I trying to print “data” row from my collection, it dosen’t work, how can i print “data” fields ?

Sincerly

Template.eveonline.helpers({ mesposts: function() { return Eveorder.find(); } });

 <ul>
 {{#each mesposts}}
   <li>{{_id}} - {{name}} - {{createdAt}} - {{data.volume}}</li>
  {{/each}}
</ul>
