http://stackoverflow.com/questions/16262065/take-only-some-value-from-javafx-observablelist
We have already an array of user data items, and we need to create another array, which will contain items of XYChart.Data type. Instead of this I suggest to give possibility to put the initial array and a factory, which, for each user data instance suggest an instance of XYChart.Data object. And chart will track changes of the intial list, and call factory for newly added items, where needed.
