Charts SAPUI5图表基于变量度量名称

我有一张图表，比较了一年和另一年的价值。我想做的是在度量的定义中使用变量，以便图例显示年份数（来自变量）。我尝试将变量分配给图表的“名称”配置，但执行此操作时出错。目前，我有它显示'开始年'和'结束年'，但真的希望它是用户正在比较的实际年份数

这是我的控制器中定义度量和馈送的部分：

I have two variables that start as the current year and the previous year, but the user can modify those values.
    var startYear = today.getFullYear();
    var endYear = today.getFullYear()-1;

var oDataset = new FlattenedDataset({
    dimensions: [{
        name: "KPI",
        value: "{field}"
        }],
    measures: [{
      name: "Start Year",   <- I tried putting startYear here and below but get errors
      value: "{current}"
    },{
      name: "End Year",       <- tried putting endYear here and below but got errors
      value: "{previous}"
    }],
    data: {
          path: "/bullet",
          filters: [oFilter]
        }
    });

    oVizFrame.setDataset(oDataset);
    oVizFrame.setModel(oModel);

    oVizFrame.setVizProperties({
        plotArea: {
            dataLabel: {
                visible: true,
                formatString: '#,##0'
            },
            colorPalette: ['sapUiChartPaletteSemanticNeutral'],
            gap: {
                visible: true
            }
        },
        valueAxis: {
            title: {
                visible: false,

            }
        },
        legend: {
            title: {
                visible: false
            }
        },
        title: {
            visible: true,
            text: 'Year Comparison'
        }
    });
  var feedValueAxis = new FeedItem({
      'uid': "valueAxis",
      'type': "Measure",
      'values': ["Start Year"]    <- tried putting startYear here but didn't work
    }),
    feedCategoryAxis = new FeedItem({
      'uid': "categoryAxis",
      'type': "Dimension",
      'values': ["KPI"]
    }),
    feedTargetValues = new FeedItem({
      'uid': "targetValues",
      'type': "Measure",
      'values': ["End Year"]       <- tried putting endYear here but got error
    });

我有两个变量，从当前年份和前一年开始，但用户可以修改这些值。
var startYear=today.getFullYear（）；
var endYear=today.getFullYear（）-1；
var oDataset=新的扁平化数据集({
尺寸：[{
名称：“KPI”，
值：“{field}”
}],
措施：[{
姓名：“开始一年”我终于做到了这一点——我想我还有一些其他问题导致这一点不起作用，但一旦我解决了这些问题，这一点就起作用了：

createDataset: function(sPath, sYr, eYr){
    return new sap.viz.ui5.data.FlattenedDataset({
        dimensions: [{
            axis : 1,
            name: "Month",
            value: "{month}"
        }],
        measures: [{              
          name: eYr,          << this contains the year I want in legend
          value: "{current}"
        },{
          name: sYr,          << this contains the year I want in legend
          value: "{previous}"
        }],

措施：[{
name:eYr，try startYear=today.getFullYear（）.toString（）；由于getFullYear返回typeof numbers，所以我尝试过，但似乎没有帮助。问题似乎在于度量值和feedValueAxis的定义中……如何将“startYear”放入？例如：doi-measures:[{name:startYear，value:：{current}“}那么FeedValueAxis是如何定义的呢？例如，我尝试了不同的变体：var FeedValueAxis=newfeedItem（{'uid'：“valueAxis”，'type'：“Measure”，'values'：startYear}）但是得到错误：uncaughtreferenceerror:startYear没有定义，这并不是我想要的，我希望“开始/结束年份”文本是实际年份，值是数据点（不是年份）。
