java - 碧 Jade 报告轴线粗细

Question

我正在自定义 Jasper Reports 生成的默认图表，但找不到使轴线变粗的方法。

到目前为止，我很容易找到更改颜色的示例: http://www.jfree.org/forum/viewtopic.php?f=3&t=11639但这更容易被编辑器更改。

我附上一张图片来说明与当前厚度相比的预期厚度。

这是我当前的定制器:

public void customize(JFreeChart jFreeChart, JRChart jrChart) {

    CategoryPlot plot = (CategoryPlot) jFreeChart.getPlot();
    plot.setRangeAxisLocation(AxisLocation.BOTTOM_OR_LEFT);


    BarRenderer barRenderer = (BarRenderer) plot.getRenderer();
    barRenderer.setItemMargin(0.0);

    NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
    NumberFormat numberFormat= NumberFormat.getNumberInstance();
    numberFormat.setMaximumFractionDigits(2);
    numberFormat.setMinimumFractionDigits(2);
    rangeAxis.setNumberFormatOverride(numberFormat);
    rangeAxis.setUpperMargin(0.2);
    rangeAxis.setAutoRange(true); //make sure that fixed range is not set
}

设置Stroke CategoryAxis 和 NumberAxis 在您的 customize 中添加以下代码:

CategoryAxis categoryAxis = plot.getDomainAxis();
categoryAxis.setAxisLineStroke(new BasicStroke(2f)); //see API link below for BasicStroke

NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
rangeAxis.setAxisLineStroke(new BasicStroke(2f));
