Thanks!  That’s exactly what I need but still run into a problem when I replace your code below:
var csvData = [
  { “label”: “Bill”, “month”: “January”, “y”: 11 },
  { “label”: “Chris”, “month”: “January”, “y”: 13 },
  { “label”: “Jesse”, “month”: “January”, “y”: 18 },
  { “label”: “Lilia”, “month”: “January”, “y”: 65 },
  { “label”: “Bill”, “month”: “February”, “y”: 7 },
  { “label”: “Chris”, “month”: “February”, “y”: 56 },
  { “label”: “Jesse”, “month”: “February”, “y”: 32 },
  { “label”: “Lilia”, “month”: “February”, “y”: 65 }
];
with this
var csvData = [];
	  $.getJSON( “JSON/tcm/data.json”, function( data){
  csvData = data;
});
When I look at the console in Chrome I don’t see any errors but I get a blank chart.
