从achartengine Android中删除标题，标签和传说

Question

我正在尝试使用Android中的achart引擎库绘制图表（如下图所示）。

DESIRED_CHART.png

这是我取得的成就

CURRENT_CHART.png

绘制此代码的代码如下

private void drawChart(){
    int[] x = { 1,2,3,4,5,6,7,8 };
    int[] happyness = { 5,2,4,1,0,4,5,0};
    int[] energy = { 5,4,3,1,4,3,5,0};
    int[] strenth = { 2,0,1,3,2,4,3,0};
    int[] endurance = { 0,2,1,4,3,5,2,0};

    // Creating an  XYSeries for Income
    XYSeries happynessSeries = new XYSeries("Happyness");
    // Creating an  XYSeries for Income
    XYSeries energySeries = new XYSeries("Energy");
    // Adding data to Income and Expense Series
    XYSeries strenthSeries = new XYSeries("Strenth");
    XYSeries enduranceSeries = new XYSeries("Endurance");

    for(int i=0;i<x.length;i++){
        happynessSeries.add(x[i], happyness[i]);
        energySeries.add(x[i],energy[i]);
        strenthSeries.add(x[i],strenth[i]);
        enduranceSeries.add(x[i],endurance[i]);
    }

    // Creating a dataset to hold each series
    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
    // Adding Income Series to the dataset
    dataset.addSeries(happynessSeries);
    // Adding Expense Series to dataset
    dataset.addSeries(energySeries);
    dataset.addSeries(strenthSeries);
    dataset.addSeries(enduranceSeries);


    // Creating XYSeriesRenderer to customize incomeSeries
    XYSeriesRenderer happynessRenderer = new XYSeriesRenderer();
    happynessRenderer.setColor(Color.parseColor("#f4ed21"));//chart border color
    happynessRenderer.setPointStyle(PointStyle.CIRCLE);
    happynessRenderer.setFillPoints(true);
    happynessRenderer.setLineWidth(2);
    happynessRenderer.setDisplayChartValues(true);
    happynessRenderer.setFillBelowLine(true);
    happynessRenderer.setFillBelowLineColor(Color.parseColor("#bbf4ed21"));

    // Creating XYSeriesRenderer to customize expenseSeries
    XYSeriesRenderer energyRenderer = new XYSeriesRenderer();
    energyRenderer.setColor(Color.parseColor("#20bff2"));
    energyRenderer.setPointStyle(PointStyle.CIRCLE);
    energyRenderer.setFillPoints(true);
    energyRenderer.setLineWidth(2);
    energyRenderer.setDisplayChartValues(true);
    energyRenderer.setFillBelowLine(true);
    energyRenderer.setFillBelowLineColor(Color.parseColor("#bb20bff2"));

    // strenth
    XYSeriesRenderer strenthRenderer = new XYSeriesRenderer();
    strenthRenderer.setColor(Color.parseColor("#f97b1d"));
    strenthRenderer.setPointStyle(PointStyle.CIRCLE);
    strenthRenderer.setFillPoints(true);
    strenthRenderer.setLineWidth(2);
    strenthRenderer.setDisplayChartValues(true);
    strenthRenderer.setFillBelowLine(true);
    strenthRenderer.setFillBelowLineColor(Color.parseColor("#bbf97b1d"));

    // endurance
    XYSeriesRenderer enduranceRenderer = new XYSeriesRenderer();
    enduranceRenderer.setColor(Color.parseColor("#c68c4d"));
    enduranceRenderer.setPointStyle(PointStyle.CIRCLE);
    enduranceRenderer.setFillPoints(true);
    enduranceRenderer.setLineWidth(2);
    enduranceRenderer.setDisplayChartValues(true);
    enduranceRenderer.setFillBelowLine(true);
    enduranceRenderer.setFillBelowLineColor(Color.parseColor("#bbc68c4d"));


    // Creating a XYMultipleSeriesRenderer to customize the whole chart
    XYMultipleSeriesRenderer multiRenderer = new XYMultipleSeriesRenderer();
    multiRenderer.setXLabels(0);
    multiRenderer.setZoomButtonsVisible(true);              
    for(int i=0;i<x.length;i++){
        multiRenderer.addXTextLabel(i+1, mMonth[i]);            
    }       
    multiRenderer.setLabelsTextSize(50);
    multiRenderer.setYLabels(0);
    multiRenderer.setMargins(new int[]{0,0,0,0});

    multiRenderer.addSeriesRenderer(happynessRenderer);
    multiRenderer.addSeriesRenderer(energyRenderer);
    multiRenderer.addSeriesRenderer(strenthRenderer);
    multiRenderer.addSeriesRenderer(enduranceRenderer);

    multiRenderer.setPanEnabled(false, false);
    multiRenderer.setZoomEnabled(false, false);
    multiRenderer.setZoomEnabled(false, false);

    // Creating an intent to plot line chart using dataset and multipleRenderer
    mChart =(GraphicalView) ChartFactory.getLineChartView(getBaseContext(), dataset, multiRenderer);

    llChart.addView(mChart);

}

第一个和最后一个x轴点数值（Mon bb 3和Mon Feb 9）正在削减。我正在努力将这些值显示为DESIRED_CHART.png

如何删除Xaxis值背后的黑色背景？

Answer 1

更改背景颜色

multiRenderer.setMarginsColor(Color.GREEN);

并给出边距以显示整个x轴点值文本

multiRenderer.setMargins(new int[]{0,40,0,40});

隐藏标题

multiRenderer.setChartTitle("");

隐藏图例

multiRenderer.setShowLegend(false);

其中multiRenderer为XYMultipleSeriesRenderer。
