Hi Myung,

The PropertyNameDataPointBinding uses reflection to access a method from the class of your data item. When the class is obfuscated, the method's name may be changed so may not be able to access it this way. Since this PropertyNameDataPointBinding class is intended to be used only as a convenience and not as a requirement for RadChartView, my suggestion is that you use the alternative DataPointBinding. Here's an example:

DataPointBinding dataPointBinding = new DataPointBinding() {
            @Override
            public Object getValue(Object o) throws IllegalArgumentException {
                return ((MyDataItem)o).getResult();
            }
        };

Don't hesitate to get back to us if you need additional assistance.
