如何在BarChart中顯示數據Android

BarChart出現問題..我列出了7個項目。例如如何在BarChart中顯示數據Android

final int[] a = {5,2,10,4,7,8,13}; 
final String[] b= {"January","February","March","April","May","June","Jully"};

所以我想在條形圖上顯示。例如前5個項目顯示，當我點擊該按鈕時，剩餘的2個項目顯示在條形圖中。圖片是，

比我想，當我點擊「WAFAW」按鈕條形圖是，

但我的代碼工作是，

所以這意味着不顯示酒吧..我該怎麼做？感謝現在..

我的代碼是，

final BarChart barChart = (BarChart) findViewById(R.id.chart); 
Button button = (Button) findViewById(R.id.button); 


final int[] a = {5,2,10,4,7,8,13}; 
final String[] b= {"January","February","March","April","May","June","Jully"}; 
final ArrayList<BarEntry> entries = new ArrayList<>(); 
final ArrayList<String> labels = new ArrayList<String>(); 

for(int i=0 ; i<5;i++){ 
    entries.add(new BarEntry(a[i],i)); 
    labels.add(b[i]); 
} 
button.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     entries.clear(); 
     labels.clear(); 

     for(int i=5; i<a.length;i++){ 
      entries.add(new BarEntry(a[i],i)); 
      labels.add(b[i]); 
     } 
     BarDataSet dataset = new BarDataSet(entries, "# of Calls"); 
     barChart.getXAxis().setPosition(XAxis.XAxisPosition.TOP); 
     BarData data = new BarData(labels, dataset); 
     dataset.setColors(ColorTemplate.COLORFUL_COLORS); 
     barChart.setData(data); 
     barChart.animateY(3000); 
    } 
}); 

BarDataSet dataset = new BarDataSet(entries, "# of Calls"); 

barChart.getXAxis().setPosition(XAxis.XAxisPosition.TOP); 

BarData data = new BarData(labels, dataset); 
dataset.setColors(ColorTemplate.COLORFUL_COLORS); 
barChart.setData(data); 

barChart.animateY(3000);
