"Stock Charts / Stock History" ( http://demos.telerik.com/kendo-ui/financial/stock-history )
In the following example $("#company-filtering-tabs").kendoTabStrip was populated by local array (dataSource: ["Google", "Apple", "Amazon"]). I wonder how can I populate it from stocksDataSource and it's distinct field symbol.
stocksDataSource is retrieve from: http://demos.telerik.com/kendo-ui/content/dataviz/dashboards/stock-data-2011.json
and it's structure goes like:
[ { "date": "3/31/2011", "close": 586.76, "volume": 2028228, "open": 583, "high": 588.1612, "low": 581.74, "symbol": "1. GOOG" },
{ "date": "3/31/2011", "close": 586.76, "volume": 2028228, "open": 583, "high": 588.1612, "low": 581.74, "symbol": "1. GOOG" }, ....
{ "date": "3/31/2011", "close": 405, "volume": 6414369, "open": 403.51, "high": 406.28, "low": 403.49, "symbol": "2. AAPL" }, ....
{ "date": "13/31/2011", "close": 382.2, "volume": 14464710, "open": 381.29, "high": 382.276, "low": 378.3, "symbol": "3. AMZN" }, ....
]
Thank you for your answers!

Please accept my apologies for the delayed response.
The problem boils down to extracting the unique values for the symbol field in the data array.
There are obviously many approaches to this problem. For example, if using loadsh we can do:
var symbols = _.uniqBy(data, 'symbol');
The best moment to do that would be in the data source change event where all the data is available.
