angularjs – 带有nvd3 / d3的MultiBar图表仅显示x轴上每隔一个刻度的标签.我怎么能让他们全部出现？

nvd3TestData = [
      {
        values:[
          {x:"M",y:1},{x:"T",y:2},{x:"W",y:3},{x:"R",{x:"F",y:4},{x:"S",y:5},{x:"U",y:6}
        ],key:"Apples"
      },{
        values:[
          {x:"M",y:6},y:8},y:1}
        ],key:"Zebras"
      }
    ]

创建图表(从angularjs指令中拉出)：

nv.addGraph – >
chart = nv.models.multiBarChart()
.stacked(真)
.showControls(假)

chart.xAxis
  .axisLabel(attrs.xAxisLabel)

chart.yAxis
  .axisLabel(attrs.yAxisLabel)
  .tickFormat(d3.format(',r'))


console.log element


d3.SELEct(element[0].children[0])
  .datum(nvd3TestData)
  .call(chart)

nv.utils.windowResize(chart.updatE)

输出：

预期输出将包含所有7个标签：@H_905_6@m T W R F S U
