achartengine上的条宽问题

Question

我的图表使用achartengine有问题。我从我的sqlite数据库中设置数据集的数据，我可以在图表上成功显示它，但条形宽度是缩小的。这是我的GenerateEngine类，用于从sqlite db生成条。

public class GenerateChart {

private ExpensesDataSource datasource;
private SpinnerValues spinnerValues = new SpinnerValues();

private SimpleDateFormat monthFormat, yearFormat;
String month, year;
List<String> values;
XYSeries series;

public XYMultipleSeriesDataset getExpensesBarDataset(Context context) {

    datasource = new ExpensesDataSource(context);

    monthFormat = new SimpleDateFormat("MM");
    month = monthFormat.format(new Date());

    yearFormat = new SimpleDateFormat("yyyy");
    year = yearFormat.format(new Date());

    datasource.openToRead();
    values = datasource.GetTotalEachCategory(month, year);
    datasource.close();

    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
    XYSeries series;
    for(int i = 0; i < spinnerValues.categoryText.length; i++) {
       series = new XYSeries(spinnerValues.categoryText[i]);
       series.add(i, Double.parseDouble(values.get(i)));

       dataset.addSeries(series);
    }
    return dataset;
}

public XYMultipleSeriesRenderer getExpensesBarRenderer() {
    XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
    renderer.setAxisTitleTextSize(16);
    renderer.setChartTitleTextSize(20);
    renderer.setLabelsTextSize(15);
    renderer.setLegendTextSize(15);
    renderer.setMargins(new int[] { 30, 40, 15, 0 });

    XYSeriesRenderer r;

    for(int i = 0; i < spinnerValues.categoryColor.length; i++) {
        r = new XYSeriesRenderer();
        r.setColor(Color.parseColor(spinnerValues.categoryColor[i]));
        r.setLineWidth(20);
        r.setFillPoints(true);
        r.setDisplayChartValues(true);
        renderer.addSeriesRenderer(r);
    }
    return renderer;
}

public void myChartSettings(XYMultipleSeriesRenderer renderer, String month, String year) {
    renderer.setChartTitle("Pratinjau Grafik Pengeluaran Bulan " + month + " Tahun " + year);
    renderer.setXAxisMin(-10);
    renderer.setXAxisMax(10);
    renderer.setYAxisMin(0);
    renderer.setYAxisMax(500000);
    renderer.setYLabelsAlign(Paint.Align.RIGHT);
    renderer.setBarSpacing(.1);
    renderer.setXTitle("Kategori");
    renderer.setYTitle("Total Pengeluaran");
    renderer.setShowGrid(true);
    renderer.setGridColor(Color.GRAY);
    renderer.setZoomButtonsVisible(true);
    renderer.setXLabels(0); // sets the number of integer labels to appear
}}

这是我从班上得到的。

我想添加条的宽度以便它正确。我将不胜感激，谢谢。

setBarWidth api用于 XYMultipleSeriesRenderer 请参阅此Api - ＆gt; API

所以在你的代码中你需要改变这个：

Inside getExpensesBarRenderer() Api
renderer.setBarWidth()
