当只有几个值时，Dimple Js 会重复打勾

Question

当我只有一两个数据点时，dimple js 会重复相同的刻度。我如何让它不那样做？

示例

<head>
  <script src="http://d3js.org/d3.v3.min.js"></script>
  <script src="http://dimplejs.org/dist/dimple.v2.1.2.min.js"></script>
</head>
<body>
  <script type="text/javascript">
    var svg = dimple.newSvg("body", 800, 600);
    var data = [
      { "Word":"1/2/1990", "Awesomeness":2000 },
      { "Word":"1/1/1990", "Awesomeness":3000 }
    ];
    var chart = new dimple.chart(svg, data);
    chart.addTimeAxis("x", "Word");
    chart.addMeasureAxis("y", "Awesomeness");
    chart.addSeries(null, dimple.plot.line);
    chart.draw();
  </script>
</body>

通常您会设置 axis.ticks but when using a time axis you'll want to set timePeriod and timeInterval。这将在数据集中每天设置一个刻度线。

var xAxis = chart.addTimeAxis("x", "Word");
xAxis.timePeriod = d3.time.days;
xAxis.timeInterval = 1;
xAxis.tickFormat = "%A";
chart.addMeasureAxis("y", "Awesomeness");
chart.addSeries(null, dimple.plot.line);
chart.draw();

Dimple Js repeats ticks when there are only a few values
