JFreechart-XYChart上的垂直X轴标签 [英] JFreechart - vertical X-axis labels on an XYChart

问题描述

我有一个XYLineChart，其中X轴上的标签是水平书写的.我希望能够垂直(降序)编写它们.

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).

我已经可以为BarCharts做到这一点了

I can already do this for BarCharts:

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

，但是XYChart返回XYPlot，而不是CategoryPlot，并且XYPlot的getDomainAxis()返回ValueAxis，而不是CategoryAxis.ValueAxis让我打电话

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);

几乎快到了！但是它使它们上升而不是下降.可以解决这个问题吗?

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

谢谢

我需要域轴保持在图表的底部.撰写原始帖子时没有考虑过其他任何方式.

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.

推荐答案

回答我自己的问题，这似乎是不可能的，所以我不得不自己将功能添加到jfreechart源中.

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