好的,我几乎整天都在破解此程序,但没有成功。我正在尝试使用JFreeChart创建XYPlot
的网格,其中图的每一列和每一行都分别链接了域轴和范围轴。也就是说,同一行中的图具有相同的范围轴范围,而一列中的图具有相同的域轴范围。
通过使用被破解的CombinedDomainXYPlot
的CombinedRangeXYPlot
的XYPlot
,我能够实现该功能。基本上,我做了一些XYPlot
对象,并将它们添加到CombinedRangeXYPlot
对象中,然后将那些CombinedRangeXYPlot
对象添加到了CombinedDomainXYPlot
的实例中,该实例未绘制域轴。 (也许还有另一种方法来代替CombinedDomainXYPlot
来堆积图,因为我没有使用组合的域轴功能。)
正如预期的那样,范围对于每一行一起缩放。通过为列中的每个子图添加相同的域轴,我可以使域针对每个列一起缩放。结果如下所示。
我现在有两个问题-首先,我想摆脱每行下方的轴标签,而只将它们放在底部,但要保持比例尺链接。
其次,范围轴的标签位于窗口的边缘-如何找回它们?
而且,总的来说,我想了解CombinedRangeXYPlot
和CombinedRangeXYPlot
如何在多个图上使用相同的轴范围,而无需在每个图下方绘制轴。

我相信,要使StackedXYPlot正常工作,我要做的另一件事就是将
CombinedDomainXYPlot.subplotAreas
的可见性更改为protected
。在这个示例中,我注意到域轴的鼠标缩放功能已关闭-但它确实传播到了该列中的其他图。
谢谢,
伊戈尔
附言我要消除该图下方的图的原因是,最后我需要绘制至少6x7的图网格,并且在这么多网格中,标签占据了大部分空间。
编辑:我已经接受了Eric的回答,认为它是功能性的,但是我正在尝试一种不太hacky的方式-How CombinedDomainXYPlot and CombinedRangeXYPlot share Axis information with subplots。如果我可以完全正常运行,我将在那里进行更新。
最佳答案
这确实是一个艰难的过程...
从您的代码开始,这就是我的接近程度:
将域轴设置为不可见:
ValueAxis a = phiDPlots[i].getDomainAxis();
a.setVisible(false);
tempPlot.setDomainAxis((NumberAxis) phiDPlots[i].getDomainAxis());
如果绘制最后一行,则设置子图的域轴可见:
// draw all the subplots
for (int i = 0; i < this.getSubplots().size(); i++) {
CombinedRangeXYPlot plot = (CombinedRangeXYPlot) this.getSubplots().get(i);
PlotRenderingInfo subplotInfo = null;
if (info != null) {
subplotInfo = new PlotRenderingInfo(info.getOwner());
info.addSubplotInfo(subplotInfo);
}
if(i==getSubplots().size()-1){ // If the last row
for(int j=0; j < plot.getSubplots().size(); j++)
((XYPlot)plot.getSubplots().get(j)).getDomainAxis().setVisible(true);
}
plot.draw(g2, this.subplotAreas[i], anchor, parentState, subplotInfo);
if(i==getSubplots().size()-1){ // If the last row
for(int j=0; j < plot.getSubplots().size(); j++)
((XYPlot)plot.getSubplots().get(j)).getDomainAxis().setVisible(false);
}
}
这行得通,但是以某种方式仅在刷新/调整窗口大小之后才能执行,因为图形的最后一行在垂直方向上过于压缩...
