带有 nvd3/d3 的 MultiBar 图表仅显示 x 轴上每隔一个刻度的标签.我怎样才能让他们全部出现? [英] MultiBar chart with nvd3 / d3 only shows labels for every other tick on the x-axis. How can I get them all to show up?

问题描述

数据:

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

创建图表(从 angularjs 指令中提取):

Creating the chart (pulled from an angularjs directive):

nv.addGraph ->图表 = nv.models.multiBarChart().stacked(真).showControls(false)

nv.addGraph -> chart = nv.models.multiBarChart() .stacked(true) .showControls(false)

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:M T W R F S U

Expected output would have all 7 labels: M T W R F S U

推荐答案

我查看了 nvd3.org 并没有找到任何真正的文档，但查看源代码，我找到了 https://github.com/novus/nvd3/blob/master/src/models/multiBarChart.js 显示一个布尔值reduceXTicks"的图表参数，带有注释，表明它会做你想做的事.我用其中一个示例图表进行了尝试，它奏效了.具体来说，我使用了:

I looked on nvd3.org and couldn't find any real documentation, but checking the source, I found https://github.com/novus/nvd3/blob/master/src/models/multiBarChart.js which showed a boolean chart parameter of "reduceXTicks" with a comment indicating it would do what you want. I tried it out with one of the example charts and it worked. Specifically, I used:

chart
   .reduceXTicks(true)
