将popup / infotip / tooltip显示为悬停特定文本

Question

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

当我将鼠标悬停在上图中右侧所示的颜色代码上时，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。

与morris地图相似：http://codepen.io/andreic/pen/CJoze

或者：http://codepen.io/anon/pen/woJMrX

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。请参考链接对于代码的当前情况：jquery plugin to bind data to a tool-tip (poshy tip)

Answer 1

对于SO来说这可能太宽泛，但这就是我喜欢创建没有任何外部库或插件的工具提示的方式。它基于创建<div>，我们将使用＆＃34; opacity＆＃34;来显示/隐藏。

首先，使用带有名为＆＃34; tooltip＆＃34;或任何其他名称的类的div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个不透明度。然后，只需在mouseover或mousemove上显示工具提示即可：

text.on("mousemove", function(d) {
    tooltip.html("Hello, I am<br>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。
