Question

在我的散点图中，有相同日期的点，但我只想注释一个。如何在我的注释数据中指定？ jsfiddle

g = new Dygraph(
document.getElementById("container"),
"Date,Temperature\n" +
"2008-05-07,75\n" +
"2008-05-08,70\n" +
"2008-05-08,20\n" +
"2008-05-09,80\n"
 );
g.ready(function() {
g.setAnnotations([
{
  series: "Temperature",
  x: "2008-05-08",
  shortText: "L",
  text: "Coldest Day"
}
]);
});

你可以这样做，在数据点上添加一秒，你不想被贴上标签。

然后我会使用格式化功能从日期中删除时间戳。＆＃39; legendFormatter＆＃39;示例：http://dygraphs.com/tests/legend-formatter.html http://dygraphs.com/tests/labelsDateMilliseconds.html http://dygraphs.com/tests/labelsDateUTC.html

g = new Dygraph(
    document.getElementById("container"),
    "Date,Temperature\n" +
    "2008-05-07,75\n" +
    "2008-05-08,70\n" +
    "2008-05-08 00:00:01,20\n" +
    "2008-05-09,80\n"
  );

  g.ready(function() {
    g.setAnnotations([
    {
      series: "Temperature",
      x: "2008-05-08",
      shortText: "L",
      text: "Coldest Day"
    }
    ]);
  });

DYGRAPHS：同一日期散点图的注释
