为什么X轴每月出备用数月而不是？

Question

以下是我的highcharts配置，你可以帮我为什么我的备用月来了，如果我想每个月显示，我该怎么做呢？此外，如果要显示每个月改变吧的宽度。

Highcharts.chart("energy_chart", {
            chart: {

另外，附接与钻取渲染highchart的屏幕截图。

，

现在，向下钻取图表（同不大不小的问题）

编辑：

它原来是一个放大的问题，即如果我够缩小（ZoomOut），那么它会显示所有点。那么，如何显示没有缩小的每一个点。

Answer 1

使用tickInterval属性并将其设置为一个月：

        xAxis: {
          type: "datetime",
          tickInterval: 30 * 24 * 3600 * 1000,
          labels: {
            step: 1
          },
          dateTimeLabelFormats: {
            day: "%e"
          }
        }
