将popup / infotip / tooltip显示为hover特定文本

我有一张图表， http：//codepen.io/Siddharth11/pen/LVQmjN

当我将鼠标hover在上图中右侧写的颜色代码上时，我想显示一个弹出窗口。

我将为每个颜色代码显示seprete信息。那么我们如何为每个颜色代码创建一个单独的弹出窗口。

类似于莫里斯地图： http ： //codepen.io/andreic/pen/CJoze

这个问题没有得到任何正确的答案。我尝试使用jquery插件（poshy提示）并试图解决问题。但是没有运气。我已经转发了问题并取得了进展。请参考链接了解当前的情况。 code： jquery插件将数据绑定到工具提示（poshy tip）

对于SO来说，这可能过于宽泛 ，但这就是我喜欢在没有任何外部库或插件的情况下创建工具提示的方式。 它基于创建

，我们将使用“不透明度”显示/隐藏。

首先，使用带有名为“tooltip”的类的div或任何其他名称设置工具提示的CSS样式：

 div.tooltip { position: absolute; /*your other styles here*/; } 

然后，设置工具提示变量：

 var tooltip = d3.select("body").append("div") .attr("class", "tooltip") .style("opacity", 0); 

这个div有0不透明度。 然后只需要在mouseover或mousemove上显示工具提示：

 text.on("mousemove", function(d) { tooltip.html("Hello, I am
a tooltip!") .style('top', d3.event.pageY - 6 + 'px') .style('left', d3.event.pageX + 10 + 'px') .style("opacity", 1); }).on("mouseout", function(d) { tooltip.style("opacity", 0); }); 

您可以使用HTML标记在工具提示中设置文本样式，使其变为粗体，斜体等。
