AChart引擎條形圖 - 向右滾動時隱藏系列

Question

我正在使用優秀的庫AChart引擎來生成條形圖。所有功能都做工精細，但我有幾件事情，我是不是能解決：

這是我的屏幕截圖：

現在有一個需要固定的兩件事情：

1）向右滾動時隱藏該系列，即使在0,0之後，當前系列March也是可見的。

2）網格線位於圖形的頂部，但它應該在圖形的後面。

3）如何在右上角而不是底部顯示圖例。

這裏是我的代碼如下：

private void openChart(){ 
     int[] x = { 10,20,30,40,50,60,70,80 }; 
     // int[] y = { 10,20,30,40,50,60,70 }; 
     int[] income = { 20,25,27,30,28,35,37,38}; 
     int[] expense = {22, 27, 29, 28, 26, 30, 33, 34 }; 
     int[] sample = {22, 27, 29, 28, 26, 30, 33, 34}; 

     // Creating an XYSeries for Income 
     XYSeries incomeSeries = new XYSeries("Income"); 
     // Creating an XYSeries for Expense 
     XYSeries expenseSeries = new XYSeries("Expense"); 
    // Creating an XYSeries for Expense 
     XYSeries sampleseries = new XYSeries("Sample"); 
     // Adding data to Income and Expense Series 
     for(int i=0;i<x.length;i++){ 
      incomeSeries.add(i,income[i]); 
      expenseSeries.add(i,expense[i]); 
      sampleseries.add(i,sample[i]); 
     } 

     // Creating a dataset to hold each series 
     XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset(); 
     // Adding Income Series to the dataset 
     dataset.addSeries(incomeSeries); 
     // Adding Expense Series to dataset 
     dataset.addSeries(expenseSeries); 
     // Adding Expense Series to dataset 
     dataset.addSeries(sampleseries); 

     // Creating XYSeriesRenderer to customize incomeSeries 
     XYSeriesRenderer incomeRenderer = new XYSeriesRenderer(); 
     incomeRenderer.setColor(Color.rgb(130, 130, 230)); 
     incomeRenderer.setFillPoints(true); 
     incomeRenderer.setLineWidth(2); 
     incomeRenderer.setChartValuesTextAlign(Align.CENTER); 
     incomeRenderer.setChartValuesTextSize(18); 
     incomeRenderer.setDisplayChartValues(true); 

     // Creating XYSeriesRenderer to customize expenseSeries 
     XYSeriesRenderer expenseRenderer = new XYSeriesRenderer(); 
     expenseRenderer.setColor(Color.rgb(220, 80, 80)); 
     expenseRenderer.setFillPoints(true); 
     expenseRenderer.setLineWidth(2); 
     expenseRenderer.setChartValuesTextAlign(Align.CENTER); 
     expenseRenderer.setChartValuesTextSize(18); 
     expenseRenderer.setDisplayChartValues(true); 

    // Creating XYSeriesRenderer to customize expenseSeries 
     XYSeriesRenderer samplseries = new XYSeriesRenderer(); 
     samplseries.setColor(Color.rgb(120, 40, 40)); 
     samplseries.setFillPoints(true); 
     samplseries.setLineWidth(2); 
     samplseries.setChartValuesTextAlign(Align.CENTER); 
     samplseries.setChartValuesTextSize(18); 
     samplseries.setDisplayChartValues(true); 


     // Creating a XYMultipleSeriesRenderer to customize the whole chart 
     XYMultipleSeriesRenderer multiRenderer = new XYMultipleSeriesRenderer(); 
     multiRenderer.setMargins(new int[]{30,50,60,0}); 
     multiRenderer.setXRoundedLabels(true); 
     multiRenderer.setLegendTextSize(24); 
     multiRenderer.setZoomRate(0.2f); 
     multiRenderer.setZoomEnabled(false, false); 
     multiRenderer.setBarSpacing(0.3f); 
     multiRenderer.setXAxisMin(-1); 
     multiRenderer.setXAxisMax(5); 
     multiRenderer.setYAxisMin(0); 
     multiRenderer.setYAxisMax(50); 
     multiRenderer.setAxisTitleTextSize(20); 
     multiRenderer.setAxesColor(Color.BLACK); 
     multiRenderer.setGridColor(Color.GRAY); 
     multiRenderer.setShowGridX(true); 
     multiRenderer.setXLabels(0); 

     multiRenderer.setPanLimits(new double[] { -1, x.length, 0, x.length}); 

     multiRenderer.setLabelsColor(Color.BLACK); 
     multiRenderer.setLabelsTextSize(20); 

     multiRenderer.setXLabelsColor(Color.BLACK); 
     multiRenderer.setXTitle("Tests"); 
     multiRenderer.setYLabelsAlign(Align.RIGHT); 
     multiRenderer.setYLabelsColor(0, Color.BLACK); 
     multiRenderer.setYTitle("Scores"); 

     for(int i=0; i< x.length;i++){ 
      multiRenderer.addXTextLabel(i, mMonth[i]); 
     } 

     // Adding incomeRenderer and expenseRenderer to multipleRenderer 
     // Note: The order of adding dataseries to dataset and renderers to multipleRenderer 
     // should be same 
     multiRenderer.addSeriesRenderer(incomeRenderer); 
     multiRenderer.addSeriesRenderer(expenseRenderer); 
     multiRenderer.addSeriesRenderer(samplseries); 

     // Creating an intent to plot bar chart using dataset and multipleRenderer 
     Intent intent = ChartFactory.getBarChartIntent(getBaseContext(), dataset, multiRenderer, Type.DEFAULT); 

     // Start Activity 
     startActivity(intent); 

    } 

Answer 1

1. renderer.setMarginsColor()和使用ACE的正確版本。
2. 隱藏它們。
3. 隱藏它或讓它按照它的方式。

更新：我還增加了一個新的API調用，將允許您以避免在圖表上部分顯示的要顯示的值。

renderer.setDisplayBoundingPoints(false); 

您可以下載包括這個功能here一個版本。
