Hi,

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.
