BoxAndWhiskerChart JFreeChart的图方向 [英] PlotOrientation of BoxAndWhiskerChart JFreeChart
问题描述
我对JFreeChart
有疑问:是否可以将BoxAndWhiskerChart
的PlotOrientation
更改为水平?我有一个直方图,我想在下面添加一个BoxAndWhiskerChart
.我需要水平放置,以便可以使用相同的轴刻度.我试图更改Plot
和ChartPanel
的方向.
I have a question about JFreeChart
: Is it possible to change the PlotOrientation
of a BoxAndWhiskerChart
to horizontal? I have a histogram, and I want to add a BoxAndWhiskerChart
below. I need it horizontal so I can use the same axis scale. I tried to change the orientation in the Plot
and ChartPanel
.
推荐答案
@卡塔利娜岛(Catalina Island)显示了更改PlotOrientation
PlotOrientation.HORIZONTAL的rel ="nofollow noreferrer"> BoxAndWhiskerRenderer
如下所示.请注意下晶须上的截断线.
@Catalina Island shows the correct way to change the PlotOrientation
here, but you may run into a bug in the BoxAndWhiskerRenderer
shown below for PlotOrientation.HORIZONTAL
. Note the truncated line on the lower whisker.
问题是drawHorizontalItem()
中此处 >
The problem is here in drawHorizontalItem()
:
g2.draw(new Line2D.Double(xxMin, yymid - halfW, xxMin, yy + halfW));
应该是这样的:
g2.draw(new Line2D.Double(xxMin, yymid - halfW, xxMin, yymid + halfW));
