LineChart | Crash if LineDataSet is empty.

[hitech95]

Hi, I just updated from beta to stable and now the activity crash. After a few of tests I have found that append if a LineDataSet is empty and is added to a LineData.

public class ChartActivity extends AppCompatActivity {
    @BindView(R.id.chart)
    LineChart mChart;

    LineData mData;
    LineDataSet mDataSet;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_chart);

        ButterKnife.bind(this);

        mData = new LineData();
        mChart.setData(mData);
        mChart.invalidate();

        mDataSet = new LineDataSet(null, "Weight");

        // If you add a value works
        mDataSet.addEntry(new Entry(0, 5));

        mData.addDataSet(mDataSet);
        mData.notifyDataChanged();
    }
}

If you don't draw the value works.

        // If you add a value works or if you disable the label
        //mDataSet.addEntry(new Entry(0, 5));
        mDataSet.setDrawValues(false);
