JFreeChart中可以有两个(X和Y)CategoryAxes吗? [英] Is it possible to have two (X and Y) CategoryAxes in JFreeChart?

问题描述

我正在JFreeChart中创建一个相关矩阵.除了两个轴都有数字值(我说1到20)之外，我几乎完成了.我将DefaultXYZDataset和自定义的BlockRenderer与重写的PaintScale类一起使用.值z本身由([1至20]，[1至20])中位置(x，y)的填充矩形的颜色表示.

I am creating a correlation matrix in JFreeChart. I'm nearly done except that both axes have number values (i: say 1 to 20). I use DefaultXYZDataset and a customized BlockRenderer with a overridden PaintScale Class. The value z itself is represented by the colour of a filled rectangle at the positions (x,y) in ([1 to 20], [1 to 20]).

是否可以用字符串(例如)替换X和Y上的轴标签.名字[i]?为此，我是否要将NumberAxes更改为CategoryAxes?因为我需要像("ParameterA"，"ParameterB")这样的坐标，所以两个轴都需要分类.我想我那时需要一个特殊的渲染器，并且必须修改整个代码.乍看之下，这甚至是不可能的.我没有找到适合该任务的数据集.

Is it possible to replace the axis labels on X and Y by a String e.g. names[i]? To achieve this, have I to change the NumberAxes into CategoryAxes? Both axes needed to be categorical since I need coordinates like ("ParameterA", "ParameterB"). I guess i would need a special renderer then and the whole code had to be modified. On first sight this isn't even possible. I didn't found a suitable Dataset for that task.

还是我可以简单地更改某种刻度标签格式?

Or could i simply change some kind of tick label format?

推荐答案

SymbolAxis (在此处所示)是NumberAxis，可能是一个合适的选择.

SymbolAxis, illustrated here, is a NumberAxis and might be a suitable choice.
