Graph 如何在google折线图中将一条线的线宽设置为零
在上面的示例中，如何为费用设置线宽=0，以便我只能看到费用线的点。实际上我需要在项目中实施。 在每个子项目中，我创建了一个折线图，在每个图中，一条线代表该科目的学生分数，另一条线包含该科目在每次考试中的最高分数。该科目中的最高分数不属于一个学生，所以我不想显示它的折线。 谢谢你在这方面的帮助 我有一个工作的例子，但它的工作时，用户点击图例文本。我希望它的工作页面加载。 https://www.google.com/jsapi“>Graph 如何在google折线图中将一条线的线宽设置为零,graph,charts,linechart,Graph,Charts,Linechart,在上面的示例中，如何为费用设置线宽=0，以便我只能看到费用线的点。实际上我需要在项目中实施。 在每个子项目中，我创建了一个折线图，在每个图中，一条线代表该科目的学生分数，另一条线包含该科目在每次考试中的最高分数。该科目中的最高分数不属于一个学生，所以我不想显示它的折线。 谢谢你在这方面的帮助 我有一个工作的例子，但它的工作时，用户点击图例文本。我希望它的工作页面加载。 https://www.google.com/jsapi“> <html> <head>
