Question

我正在使用Java FX创建折线图。在更新时，我有一个复选框列表，用于选择或取消选择一系列折线图。如果取消选择所有内容但是通过再次执行相同的操作或者为折线图添加新数据，那里的刻度点或动画刻度点等等也是相同的。我无法添加图片以方便您使用。请帮忙。

private static void printChartAnalysis（analysisResults r）{

    clearAnalsisChartData();
    int [][]analysisResult=r.getAnalysisResult();
    ArrayList<String> versionss=r.getVersions();
    int k=0;
    for(String x:versionss){
        String z=new String();
        for(int i=0;i<x.length();i++){
            if(Character.isDigit(x.charAt(i))){
                z+=x.charAt(i);
            }
        }
        dataLOC.add(new XYChart.Data(z,(int)analysisResult[k][0]));
        dataComm.add(new XYChart.Data(z,(int)analysisResult[k][1]));
        dataCond.add(new XYChart.Data(z,(int)analysisResult[k][2]));
        dataLoops.add(new XYChart.Data(z,(int)analysisResult[k][3]));
        dataMem.add(new XYChart.Data(z,(int)analysisResult[k][4]));
        k++;
    }

    seriesLOC.setData(dataLOC);
    seriesCond.setData(dataCond);
    seriesComm.setData(dataComm);
    seriesLoop.setData(dataLoops);
    seriesMem.setData(dataMem);        
    lineChart.getData().setAll(seriesLOC,seriesComm,seriesCond,seriesLoop,seriesMem);
    lineChart.setTitle("Line Chart for "+r.getSoftwareName());

    for (int i = 0; i < names.length; i++) {
        final CheckBox cb = cbs[i];
        cb.setSelected(true);
    }

}

private static void printChartCost(cocomoResults est){
    clearAnalsisChartData();
    clearCostChartData();
    for(COCOMO cost:est.getVersionsResult()){
         String version=cost.getVersion();
         String z=new String();

         for(int i=0;i<version.length();i++){
            if(Character.isDigit(version.charAt(i))){
                z+=version.charAt(i);
            }
        }

        dataEffort.add(new XYChart.Data(z,(int)cost.getEffort()));
        dataDura.add(new XYChart.Data(z,(int)cost.getDuration()));
        dataStaff.add(new XYChart.Data(z,(int)cost.getStaff()));
        dataProd.add(new XYChart.Data(z,(int)cost.getProductivity()));

    }

    seriesEffort.setData(dataEffort);
    seriesDura.setData(dataDura);
    seriesStaff.setData(dataStaff);
    seriesProd.setData(dataProd);

    lineChart.getData().setAll(seriesEffort,seriesDura,seriesStaff,seriesProd);

}

private static void clearAnalsisChartData(){
    lineChart.getData().removeAll(seriesLOC);
    lineChart.getData().removeAll(seriesComm);
    lineChart.getData().removeAll(seriesCond);
    lineChart.getData().removeAll(seriesLoop);
    lineChart.getData().removeAll(seriesMem);

    dataLOC.clear();
    dataLoops.clear();
    dataComm.clear();
    dataCond.clear();
    dataMem.clear();

}

Answer 1

据我了解

cb.setOnAction(event -> {
   if (lineChart.contains(*NAME_OF_YOUR_ELEMENT*))
      lineChart.remove(*NAME_OF_YOUR_ELEMENT*)
   else
      lineChart.remove(*NAME_OF_YOUR_ELEMENT*)
});

lineChart使用JavaFx
