@agpt Yes. The names property is a good way to go generally because the first property of the columns data array eg 'd1' above is used when doing things like having multiple types on charts. eg for a bar and line combination using types instead of type: 'pie':

columns: [
   ['bar_1', 3, 8, 6],
   ['bar_2', 4, 0, 7],
   ['bar_3', 2, 3, 0] 
],

types: {
  bar_1: 'bar',
  bar_2: 'line',
  bar_3: 'bar'
},

names : {
      bar_1: 'Initial',
      bar_2: '3 month',
      bar_3: '6 month'                
}

So, using the names property allows you to use more 'dynamic' property names and be consistent throughout the config.
