【问题描述】：

我正在努力禁用默认的悬停文本。我已经添加了自定义悬停文本，但除了自定义文本之外，默认值仍然显示。我试过 hoverinfo = 'none' 和 hoverinfo = ''。在上面的屏幕截图中，箭头指向默认的悬停文本。有没有办法禁用该文本？

这是我的代码：

temp <- structure(list(therapy_class = structure(c(1L, 1L, 1L, 1L, 1L,

【问题讨论】：

@YBS 我要显示的信息在绿框内，即 3 行。在框外，它再次显示了治疗课程。屏幕截图中的箭头指向我不想显示的行。

【解决方案1】：

plot_ly(
    data = temp,
    y = ~value,
    x = ~Year_month,
    color = ~therapy_class,
    name = ""
)

需要将名称参数传递为“”。它使用默认值并在悬停信息中使用它。
