@Override
            public void onValueSelected(int bubbleIndex, BubbleValue value) {
                Toast.makeText(getActivity(), "Selected: " + value, Toast.LENGTH_SHORT).show();
            }
To animate values you have to change targets values and then call {@link Chart#startDataAnimation()}
method(don't confuse with View.animate()).
