MPAndroidChart 组合图表 ScatterGraph 和 LineGraph

如何解决MPAndroidChart 组合图表 ScatterGraph 和 LineGraph

我没有编程背景，但我有一个作业，我应该将数据的 ScatterGraph 和 LineGraph 组合起来以连接散点。我曾尝试查看另一份参考资料，但我无法将其应用到我的作业中，而且我找不到任何关于 CombinedChart 的教程。

我需要帮助告诉我应该如何写下我的 Java 代码，因为我真的不知道如何写下来。

好吧，这是我现在的代码，但只是 ScatterGraph :

public class hasill1 extends AppCompatActivity  {
private static final String TAG = "hasill1";


private Float pnmaks,mntar,pntar,pntek,mntek,mnsei,pnsei,mnnull;
private ScatterChart mScatter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_hasill1);

    mScatter = findViewById(R.id.scatter);

    setData();
}

private void setData() {

ArrayList<Entry> dataSet = new ArrayList<Entry>();
        Intent intent= getIntent();
        float pnmaks = (float) intent.getDoubleExtra("pnmaks",0.00);
        float mntek = (float) intent.getDoubleExtra("mntek",0.00);
        float pntek = (float) intent.getDoubleExtra("pntek",0.00);
        float mnsei = (float) intent.getDoubleExtra("mnsei",0.00);
        float pnsei = (float) intent.getDoubleExtra("pnsei",0.00);
        float mntar = (float) intent.getDoubleExtra("mntar",0.00);
        float pntar = (float) intent.getDoubleExtra("pntar",0.00);
        float mnnull = (float) intent.getDoubleExtra("mnnull",0.00);



        dataSet.add(new Entry(0,pnmaks));
        dataSet.add(new Entry(mntek,pntek));
        dataSet.add(new Entry(mnsei,pnsei));
        dataSet.add(new Entry(mntar,pntar));
        dataSet.add(new Entry(mnnull,0));


        ArrayList<Entry> dataSet2 = new ArrayList<Entry>();

        float pnmaksd = (float) intent.getDoubleExtra("pnmaksd",0.00);
        float mntekd = (float) intent.getDoubleExtra("mntekd",0.00);
        float pntekd = (float) intent.getDoubleExtra("pntekd",0.00);
        float mnseid = (float) intent.getDoubleExtra("mnseid",0.00);
        float pnseid = (float) intent.getDoubleExtra("pnseid",0.00);
        float mntard= (float) intent.getDoubleExtra("mntard",0.00);
        float pntard = (float) intent.getDoubleExtra("pntard",0.00);
        float mnnulld = (float) intent.getDoubleExtra("mnnulld",0.00);



        dataSet2.add(new Entry(0,pnmaksd));
        dataSet2.add(new Entry(mntekd,pntekd));
        dataSet2.add(new Entry(mnseid,pnseid));
        dataSet2.add(new Entry(mntard,pntard));
        dataSet2.add(new Entry(mnnulld,0));

    ArrayList<Entry> dataSet3 = new ArrayList<Entry>();

    float Mu = (float) intent.getDoubleExtra("Mu",0.00);
    float Pu = (float) intent.getDoubleExtra("Pu",0.00);


    dataSet3.add(new Entry(Mu,Pu));


        ScatterDataSet set1,set2,set3;
        set1= new ScatterDataSet(dataSet,"Kuat Nominal");
        set1.setColor(Color.RED);
        set1.setValueTextSize(15);
        set1.setDrawValues(true);

        set2= new ScatterDataSet(dataSet2,"Kuat Desain");
        set2.setDrawValues(true);

        set3= new ScatterDataSet(dataSet3,"Mu - PU");
        set3.setColor(Color.GREEN);
        set3.setValueTextSize(15);
        set3.setDrawValues(true);

        ScatterData data = new ScatterData(set1,set3);

        mScatter.setData(data);
        mScatter.getDescription().setText("Diagram Interaksi Kolom");
        mScatter.animateY(2000);
}

}

我非常感谢您的帮助！谢谢:)
