Highstocks - 悬停在一个点上时显示年份

Question

在 highstocks 演示中 - https://www.highcharts.com/stock/demo/basic-line - 当鼠标悬停在一个点上时，您可以看到工具提示出现在底部，其中包含日、月和年。

但是在我的演示中 - http://jsfiddle.net/czsLpfp0/2/ - 你可以看到没有显示年份。

谁能解释一下我是如何在 'tooltip' 中显示年份的？

Answer 1

您可以在图表的主要选项中指定tooltip.xDateFormat

tooltip: {    
    xDateFormat: '%A, %b %d,%Y'
}

// Create the chart
Highcharts.stockChart('container', {
  "foo": 2,
  "chart": {
    "zoomType": "x"
  },
  "exporting": {
    "enabled": false
  },

    "enabled": true
  },

    "enabled": true
  },
