单击按钮后更改饼图 (AnyChart)

如何解决单击按钮后更改饼图 (AnyChart)

我正在尝试开发一个应用程序，一旦单击按钮，AnyChart 中的饼图就会显示新数据。我已经检查过按钮是否工作正常，但是当我点击按钮时，每次都会显示相同的 pir 图。

这是我的java代码：

public class MainActivity extends AppCompatActivity {
AnyChartView anyChartView,anyChartView1,anyChartView2,anyChartView3;
private Button button1,button2,button3,button4;

String [] months = {"Temp","Flow","Pres","Elec"};
int [] earning = {500,800,300,900};

String [] pres1 = {"Temp","Elec"};
int [] pres2 = {200,100,1000,400};

String [] elec1 = {"Temp","Elec"};
int [] elec2 = {600,700,900,1000};

String [] flow1 = {"Temp","Elec"};
int [] flow2 = {4000,400,500};

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

    anyChartView = findViewById(R.id.any_chart_view);
    anyChartView1 = findViewById(R.id.any_chart_view1);
    anyChartView2 = findViewById(R.id.any_chart_view2);
    anyChartView3 = findViewById(R.id.any_chart_view3);

    button1 = (Button) findViewById(R.id.button1);
    button2 = (Button) findViewById(R.id.button2);
    button3 = (Button) findViewById(R.id.button3);
    button4 = (Button) findViewById(R.id.button4);

    button1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            setupPieChart();
        }
    });

    button2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            setupPieChart1();
        }
    });

    button3.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            setupPieChart2();
        }
    });

    button4.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            setupPieChart3();
        }
    });
}

private void setupPieChart3() {
    Pie pie3 = AnyChart.pie();
    APIlib.getInstance().setActiveAnyChartView(anyChartView);
    List<DataEntry> dataEntries1 = new ArrayList<>();
    for (int j = 0; j < flow1.length; j++){
        dataEntries1.add(new ValueDataEntry(flow1[j],flow2[j]));
    }
    pie3.data(dataEntries1);
    pie3.title("Flow");
    anyChartView.setChart(pie3);
}

private void setupPieChart2() {
    Pie pie2 = AnyChart.pie();
    APIlib.getInstance().setActiveAnyChartView(anyChartView3);
    List<DataEntry> dataEntries2 = new ArrayList<>();
    for (int k = 0; k < elec1.length; k++){
        dataEntries2.add(new ValueDataEntry(elec1[k],elec2[k]));
    }
    pie2.data(dataEntries2);
    pie2.title("Electricity");
    anyChartView3.setChart(pie2);
}

private void setupPieChart1() {
    Pie pie1 = AnyChart.pie();
    APIlib.getInstance().setActiveAnyChartView(anyChartView2);
    List<DataEntry> dataEntries3 = new ArrayList<>();
    for (int l = 0; l < pres1.length; l++){
        dataEntries3.add(new ValueDataEntry(pres1[l],pres2[l]));
    }
    pie1.data(dataEntries3);
    pie1.title("Pressure");
    anyChartView2.setChart(pie1);
}

private void setupPieChart() {

    Pie pie = AnyChart.pie();
    APIlib.getInstance().setActiveAnyChartView(anyChartView1);
    List<DataEntry> dataEntries = new ArrayList<>();
    for (int i = 0; i < months.length; i++){
        dataEntries.add(new ValueDataEntry(months[i],earning[i]));
    }
    pie.data(dataEntries);
    pie.title("Temperature");
    anyChartView1.setChart(pie);
}

}

这是绘制图形时屏幕的外观。

我想在单击不同按钮后更改图表。任何帮助将不胜感激。
