JFreechart - vertical X-axis labels on an XYChart

Question

I have an XYLineChart, where the labels on the X axis are written horizontally. I would like to be able to write them vertically (descending).

I can already do this for BarCharts:

CategoryPlot plot = (CategoryPlot) chart.getPlot();
final CategoryAxis domainAxis = plot.getDomainAxis();
domainAxis.setCategoryLabelPositions(CategoryLabelPositions.DOWN_90);

but an XYChart returns an XYPlot, rather than a CategoryPlot, and the getDomainAxis() of an XYPlot returns a ValueAxis, not a CategoryAxis. ValueAxis lets me call

setVerticalTickLabels(true);

which is almost there! But it draws them ascending, rather than descending. Any way around this?

Thanks,

Edit: I need the domain axis to stay at the bottom of the chart. Hadn't considered it being any other way when making the original post.

ValueAxis does this automatically in drawTickMarksAndLabels() for an axis on the RectangleEdge.TOP edge:

xyPlot.setDomainAxisLocation(AxisLocation.TOP_OR_LEFT);

enter image description here

Example based on a variation of ScatterAdd.

Thanks. I need the labels on the bottom, rather than the top, though. I've had to modify the source to achieve this. – woddle Dec 12 '11 at 09:04

Answering my own question, this didn't seem to be possible, so I had to add the functionality to the jfreechart source myself.
