对Jfreechart生成的条形图的影响

Question

我是JFreechart的新手，我制作了一个条形图。酒吧里面有一条闪亮的线条。我想知道是否有可能在栏中摆脱这条线。我希望这些条纹具有遮罩效果。我附上了我生成的条形图的图像。任何指针都会有很大的帮助。

先谢谢。

SSCCE：

public JFreeChart createBarChart(CategoryDataset dataset) {
    // TODO Auto-generated method stub
    String unter_title="No of counts";
    JFreeChart jfreechart = ChartFactory.createBarChart(title, unter_title, "frequencies", dataset, PlotOrientation.VERTICAL, true, true, false);
    String text="Test Start Time: "+(new Date(test.getStart_utc_timestamp()).toString()+" "+"Test End Time: "+new Date(test.getEnd_utc_timestamp()));
    jfreechart.addSubtitle(new TextTitle(text, new Font("Dialog", 3, 10)));
    CategoryPlot categoryplot = (CategoryPlot)jfreechart.getPlot();
    categoryplot.setDomainGridlinesVisible(true);
    categoryplot.setRangePannable(true);
    NumberAxis numberaxis = (NumberAxis)categoryplot.getRangeAxis();
    numberaxis.setNumberFormatOverride(NumberFormat.getPercentInstance());
    numberaxis.setUpperMargin(0.10000000000000001D);

    BarRenderer barrenderer = (BarRenderer)categoryplot.getRenderer();
    barrenderer.setDrawBarOutline(false);
    barrenderer.setSeriesPaint(0, Color.DARK_GRAY);

    barrenderer.setMaximumBarWidth(0.0500000000000000001D);
    barrenderer.setLegendItemToolTipGenerator(new StandardCategorySeriesLabelGenerator("Tooltip: {0}"));
    CategoryAxis categoryaxis = categoryplot.getDomainAxis();
    return jfreechart;
}

突出显示是GradientBarPainter的一项功能。相反，请按照建议here尝试StandardBarPainter。
