GraphView不显示折线图

Question

有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>

有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);
    }
}

我知道数据是从数组weightDiaryList收集的，但是图中的线未显示。如果我将x和y替换为5和10，则一切正常。

如果我使用series.setDrawDataPoints(true)，则指向正确显示。

如何解决？如何显示该图的线？

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);
