通过Java代码在jasper Report中进行类别轴标签表达对齐

Question

Is there any way, to change Category Axis Label Expression's Alignment of a Chart in Jasper Report through Java Code. I want Left alignment of Category Axis Label Expression. As shown the picture below, I want "hello" to be left aligned.

Answer 1

Starting with BarChartDemo1 , included in the distribution, the changes below create a bar chart with an axis label having its location set to the LOW_END . For PlotOrientation.VERTICAL , that means aligned on the left.

JFreeChart chart = ChartFactory.createBarChart(
    "Performance: JFreeSVG vs Batik",
    "$P{hello}" /* x-axis label*/,
    "Milliseconds" /* y-axis label */,
    dataset, PlotOrientation.VERTICAL, false, false, false);
…
CategoryPlot plot = (CategoryPlot) chart.getPlot();
CategoryAxis domainAxis = plot.getDomainAxis();
domainAxis.setLabelLocation(AxisLabelLocation.LOW_END);

Try doing the same for the range axis to see the effect:

rangeAxis.setLabelLocation(AxisLabelLocation.LOW_END);
