Java JFreeChart类别步骤图水平（图像解释）(Java JFreeChart Category Step Chart horizontal (image to explane))

 我需要以下类型的图表： 
 它应该是一个“竖立”的折线图，纵轴上有类别，如下所示： 
 
 
 我发现这个类别步骤图的例子，但它的方向不适合我的目的。 

 
 http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/renderer/category/CategoryStepRenderer.html 
 

 到目前为止，我所做的只是这一点，但正如你所看到的，红线不适合图表的方向（应该是水平的）： 

 
 相应的代码如下： 
 
   DefaultCategoryDataset ds = new DefaultCategoryDataset(); 

// create dataset

    for (int k = 0; k < ffCount; k++) {
                  StateSignal ss1 = (StateSignal) this.ffDSet.getFframes().get(k).getSignals().get(i);
                  ds.setValue((double) k + 1, ss1.getName(), ss1.getStates().get(0).getStatus());

     }
    CategoryStepRenderer categorysteprenderer = new CategoryStepRenderer(false);
    categorysteprenderer.setBaseToolTipGenerator(new StandardCategoryToolTipGenerator());
    CategoryAxis categoryaxis = new CategoryAxis("Category");
    NumberAxis numberaxis = new NumberAxis("Value");
    CategoryPlot categoryplot = new CategoryPlot(ds, categoryaxis, numberaxis, categorysteprenderer);
    categoryplot.setRangePannable(true);
    categoryplot.setOrientation(PlotOrientation.HORIZONTAL);
    chart = new JFreeChart("test", null, categoryplot, true);
 
 我没有得到它的工作。 有任何想法吗？ 
 
 提前致谢！ 


 i need the following type of chart:
 It should be a "steped" line chart with categories on the vertical axis, like this:
 
 
I found this example of an Category Step Chart, but it the orientation is not right for my purpose.

 
http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/renderer/category/CategoryStepRenderer.html 
 

 All i have done so far is this, but as you can see the red line does not fit to the orientation of the chart(should be horizontal): 

 
 
The corresponding code to this:
 
   DefaultCategoryDataset ds = new DefaultCategoryDataset(); 

// create dataset

    for (int k = 0; k < ffCount; k++) {
                  StateSignal ss1 = (StateSignal) this.ffDSet.getFframes().get(k).getSignals().get(i);
                  ds.setValue((double) k + 1, ss1.getName(), ss1.getStates().get(0).getStatus());

     }
    CategoryStepRenderer categorysteprenderer = new CategoryStepRenderer(false);
    categorysteprenderer.setBaseToolTipGenerator(new StandardCategoryToolTipGenerator());
    CategoryAxis categoryaxis = new CategoryAxis("Category");
    NumberAxis numberaxis = new NumberAxis("Value");
    CategoryPlot categoryplot = new CategoryPlot(ds, categoryaxis, numberaxis, categorysteprenderer);
    categoryplot.setRangePannable(true);
    categoryplot.setOrientation(PlotOrientation.HORIZONTAL);
    chart = new JFreeChart("test", null, categoryplot, true);
 
I don´t get it to work. Any ideas?
 
Thanks in advance!
