GraphView not showing line graph

There is xml:

<?xml version="1.0" encoding="utf-8"?>
<com.jjoe64.graphview.GraphView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="200dip"
    android:id="@+id/graph">

</com.jjoe64.graphview.GraphView>

There is java:

LineGraphSeries<DataPoint> series;

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

    GraphView graph = findViewById(R.id.graph);
    for (int i = 0; i < FragmentDiaryWeight.weightDiaryList.size(); i++) {
        series = new LineGraphSeries<>(new DataPoint[]{
                new DataPoint(Integer.parseInt(FragmentDiaryWeight.weightDiaryList.get(i).getmDay()), Integer.parseInt(FragmentDiaryWeight.weightDiaryList.get(i).getmWeight())),
        });
        graph.addSeries(series);
    }
}

I know that data are collected from Array weightDiaryList, but line of graph not showing. If I replace x and y for, example, 5 and 10, all is ok.

If I using series.setDrawDataPoints(true), point showing correctly.

How can I fix it? How to display line for this Graph?
