achart引擎設置

Question

我試過使用achart引擎，但文檔有點不清楚。我也試着看過這些例子。

有人可以解釋如何增加附加的條形圖中的線的粗細？另外，我想將每個欄分成它自己的系列，但我沒有這樣做（我的代碼在圖片下方）。我一直在研究這個問題很長一段時間！

public XYMultipleSeriesRenderer getBarDemoRenderer() { 
    Log.d(LOG_TAG, "Entering getBarDemoRenderer"); 
    XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer(); 
    renderer.setAxisTitleTextSize(18); 
    renderer.setChartTitleTextSize(20); 
    renderer.setLabelsTextSize(18); 
    renderer.setLegendTextSize(14); 
    renderer.setMargins(new int[] {20, 30, 15, 0}); 
    int[] color = {Color.RED, Color.CYAN,Color.YELLOW, Color.LTGRAY,Color.MAGENTA, Color.GREEN, Color.WHITE}; 

    for(int i=0; i<7; i++){ 
     SimpleSeriesRenderer r = new SimpleSeriesRenderer(); 
     r.setColor(color[i]); 
     renderer.addSeriesRenderer(r); 
    } 

    int renderCount = renderer.getSeriesRendererCount(); 
    Log.d(LOG_TAG, "Renderer series count = " + renderCount); 

    return renderer; 
} 

private XYMultipleSeriesDataset getApplianceDataset() { 

    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset(); 

    try{ 

     CategorySeries series = null; 
     for (Map.Entry<String,Float> entry : list.entrySet()) { 
      String key = entry.getKey(); 
      series = new CategorySeries (key); 
      String b=String.valueOf(entry.getValue()); 
      double value=Double.valueOf(b); 
      series.add(value); 
      dataset.addSeries(series.toXYSeries()); 
     } 

    }catch(IllegalArgumentException e){ 
     Log.e(LOG_TAG, "IllegalArgumentException " + e.toString()); 
     Toast.makeText(this, "Unable to show chart", Toast.LENGTH_LONG).show(); 
    } 

    int dataSeriesCount = dataset.getSeriesCount(); 
    return dataset; 
} 


    private void setChartSettings(XYMultipleSeriesRenderer renderer) {   
     renderer.setChartTitle("Test Bar Chart"); 
     renderer.setChartTitleTextSize(20); 
     renderer.setXTitle("Appliance"); 
     renderer.setYTitle("Watt Hours (wh)"); 
     renderer.setXAxisMax(3); 
     renderer.setXAxisMin(0.0); 
     renderer.setYAxisMax(1800); 
     renderer.setYAxisMin(0); 
    } 

Answer 1

在setChartSettings給

 renderer.setBarSpacing(1.0f); 
     renderer.setMargins(new int[] {10, 10, 10, 0});
