    <p>I'm trying to convert a csv with data in months format to quarter format (avg for quarter, not sum..)</p> <p>The output I need is a nested array, as shown below for the months, only for quarters. I've already calculated each quarter for month using the d3.nest function, but I can't seem to get it converted to quarters.</p> <p>Here is the csv with the data:</p> <pre><code>x,January,February,March,April,May,June,July Overall,3635,3371,3474,4212,4815,5544,4464 A,1689,1489,1588,2231,2419,2889,2304 B,316,266,267,323,337,354,435 C,622,537,629,614,766,720,616 </code></pre> <p>Here is the code that nests the data:</p> <pre><code>nest = d3.nest().key(function(d) { return d.x; }) .rollup(function(leaves) { var a = []; d3.entries(leaves[0]).forEach(function (k) { if (k.key != "x") a.push({x: k.key, y: k.value, month: k.key, quater: (Math.floor((new Date(Date.parse(k.key + "1, 2013")).getMonth()+1)/3+1))}); }); return a; }); data = nest.entries(data); </code></pre> <p>Which results in (stipped to fit..):</p> <pre><code>[ { "key":"Overall", "values":[ { "x":"January", "y":"3635", "month":"January", "quater":1 }, { "x":"February", "y":"3371", "month":"February", "quater":1 }, { "x":"March", "y":"3474", "month":"March", "quater":2 }, { "x":"April", "y":"4212", "month":"April", "quater":2 }, { "x":"May", "y":"4815", "month":"May", "quater":2 }, { "x":"June", "y":"5544", "month":"June", "quater":3 }, { "x":"July", "y":"4464", "month":"July", "quater":3 } ] }, { "key":"A", "values":[ { "x":"January", "y":"1689", "month":"January", "quater":1 }, { "x":"February", "y":"1489", "month":"February", "quater":1 }, { "x":"March", "y":"1588", "month":"March", "quater":2 }, { "x":"April", "y":"2231", "month":"April", "quater":2 }, { "x":"May", "y":"2419", "month":"May", "quater":2 }, { "x":"June", "y":"2889", "month":"June", "quater":3 }, { "x":"July", "y":"2304", "month":"July", "quater":3 } ] }, { "key":"B", "values":[ { "x":"January", "y":"316", "month":"January", "quater":1 }, { "x":"February", "y":"266", "month":"February", "quater":1 }, { "x":"March", "y":"267", "month":"March", "quater":2 }, { "x":"April", "y":"323", "month":"April", "quater":2 }, { "x":"May", "y":"337", "month":"May", "quater":2 }, { "x":"June", "y":"354", "month":"June", "quater":3 }, { "x":"July", "y":"435", "month":"July", "quater":3 } ] }, { "key":"C", "values":[ { "x":"January", "y":"622", "month":"January", "quater":1 }, { "x":"February", "y":"537", "month":"February", "quater":1 }, { "x":"March", "y":"629", "month":"March", "quater":2 }, { "x":"April", "y":"614", "month":"April", "quater":2 }, { "x":"May", "y":"766", "month":"May", "quater":2 }, { "x":"June", "y":"720", "month":"June", "quater":3 }, { "x":"July", "y":"616", "month":"July", "quater":3 } ] } ] </code></pre> <p>Thanks in advance for the helpers!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
