如何在條形圖上繪製軸之間的虛線android

Question

我正在使用achartengine jar進行條形圖視圖。我的條形圖設計示例圖要求如下。

• 將頂部圖像我requiremnt條形圖
• 底部圖片是我的輸出圖像。

我的代碼是：

public class TestClass extends AppCompatActivity { 
    private GraphicalView BarChartView; 

    @SuppressLint("ParserError") 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_graph); 
     if (BarChartView==null) 
     { 

      XYMultipleSeriesRenderer renderer = buildBarRenderer(); 
      setChartSettings(renderer); 
      BarChartView = ChartFactory.getBarChartView(this, getBarDataset(), renderer, Type.DEFAULT); 
      LinearLayout playout = (LinearLayout) findViewById(R.id.graph2); 
      playout.addView(BarChartView); 

     } else 
     { 
      BarChartView.repaint(); 
      BarChartView.setVisibility(View.GONE); 
     } 
    } 

    private void setChartSettings(XYMultipleSeriesRenderer renderer) 
    { 
     renderer.setYTitle("Hits"); 
     renderer.setXAxisMin(0); 
     renderer.setXAxisMax(7); 
     renderer.setYAxisMin(0); 
     renderer.setYAxisMax(100); 

    } 
    private XYMultipleSeriesDataset getBarDataset() 
    { 
     XYSeries series1 = new XYSeries("A"); 
     XYSeries series2 = new XYSeries("B"); 
     XYSeries series3 = new XYSeries("C"); 
     XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset(); 

     series1.add(3, 50); 
     dataset.addSeries(series1); 

     series2.add(4, 25); 
     dataset.addSeries(series2); 

     series3.add(5, 100); 
     dataset.addSeries(series3); 

     return dataset; 

    } 
    protected XYMultipleSeriesRenderer buildBarRenderer() { 
     XYMultipleSeriesRenderer mrenderer = new XYMultipleSeriesRenderer(); 

     //double[] range = {5,5,0}; 

     mrenderer.setAxisTitleTextSize(16); 
     mrenderer.setChartTitleTextSize(20); 
     mrenderer.setLabelsTextSize(15); 
     mrenderer.setLegendTextSize(15); 
     mrenderer.setBarSpacing(0.5); 
     mrenderer.setXLabels(0); 
     mrenderer.addXTextLabel(0, "SAVINGS TOTAL"); 
     mrenderer.addXTextLabel(1.5, "SPEND BREAKDOWN"); 
     mrenderer.addXTextLabel(3, "DEPT"); 
     mrenderer.setMargins(new int[]{20, 30, 15, 0}); 
     mrenderer.setAxesColor(Color.WHITE); 
     mrenderer.setChartTitle(""); 
     mrenderer.setXTitle(""); 
     // mrenderer.setInitialRange(range, 1); 
     mrenderer.setBarWidth(100); 

     XYSeriesRenderer renderer1 = new XYSeriesRenderer(); 
     renderer1.setColor(Color.GREEN); 
     XYSeriesRenderer renderer2 = new XYSeriesRenderer(); 
     renderer2.setColor(Color.RED); 
     XYSeriesRenderer renderer3 = new XYSeriesRenderer(); 
     renderer3.setColor(Color.BLUE); 
     mrenderer.addSeriesRenderer(renderer1); 
     mrenderer.addSeriesRenderer(renderer2); 
     mrenderer.addSeriesRenderer(renderer3); 

     return mrenderer; 

    } 


} 

請請幫我解決吧Grapg點綴X和Y軸之間的線。 如果有人有想法，請告訴我。提前致謝。

使用

renderer.setStroke(BasicStroke.DASHED); 

或

renderer.setStroke(BasicStroke.DOTTED);
