• In this example we will create a dataProvider object that can be used with amCharts. We will assume that we have a collection named "test" and a view named "view" with a variable named "var" that has the values 1, 2, and 3. In this example we will run a tabulation that will count the frequencies of each of these values that could be used to create a chart.

• Running the tabulation would normally look something like this:

  Code Block
  title Tabulation
  http://{host}/rds/test/view/tabulate?dims=var

  Code Block
  title Tabulation Output
  { "records": [ [ 1, 182 ], [ 2, 354 ], [ 3, 126 ] ], "info": { "colCount": 2, "format": "MTNA", "includeMetadata": false, "limit": 20, "offset": 0, "moreRows": false } }

• We can add the format parameter to specify we want this to be output in a way that amCharts expects us to see it. 

  Code Block
  title Tabulation amCharts
  http://{host}/rds/test/view/tabulate?dims=var&format=amcharts

  Code Block
  title Tabulation amCharts Output
  { "dataProvider": [ { "var": 1, "count": 182 }, { "var": 2, "count": 354 }, { "var": 3, "count": 126 } ] }
