javascript - 谷歌图表 : Adding stroke to points

Question

我想在我的 Google 折线图中的点周围添加一笔画。

来自points-documentation Google Charts(底部)我们有:

The following style customizations are available: [...] - stroke-color (Specified as a hex string.) - stroke-width (Specified as a hex string.)

我找不到有关如何添加这些选项的文档。任何人，谁能弄清楚？

借用谷歌的一个例子(参见 https://jsfiddle.net/j9sgdr4d/)

var data = google.visualization.arrayToDataTable
        ([['X', 'Y', {'type': 'string', 'role': 'style'}],
          [1, 3, null],
          [2, 2.5, null],
          [3, 3, null],
          [4, 4, null],
          [5, 4, 'point { size: 18; shape-type: star; fill-color: #a52714'],
          [6, 3, 'point { size: 18; shape-type: star; fill-color: #a52714; stroke-color: #ff0000; stroke-width: 5'],
          [7, 2.5, null],
          [8, 3, null]
    ]);
