javascript - display popup/infotip/tooltip as hover a particular text

Question

I have a chart, http://codepen.io/Siddharth11/pen/LVQmjN

I want to display a popup as I hover over the color codes written on right side in the above chart.

I will be displaying seprete info for each color code.So how can we create a sepeate popup for each color code.

Similar to a morris map : http://codepen.io/andreic/pen/CJoze

or this :http://codepen.io/anon/pen/woJMrX

This question didnot fetch any correct response yet.i tried using a jquery plugin(poshy tip) and tried to solve the issue.yet no luck.I had reposted the question with the progress made.Kindly refer the link for the current situation with the code : jquery plugin to bind data to a tool-tip (poshy tip)

Answer 1

This is probably too broad for SO, but this is how I like to create tooltips without any external library or plugin. It's based on creating a <div>, that we will show/hide using "opacity".

First, set the CSS style for the tooltip, using a div with a class named "tooltip", or any other name:

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

Then, set a tooltip variable:

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

This div has 0 opacity. Then it's just a matter of showing the tooltip on mouseover or mousemove:

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);
    });

You can use HTML tags to style your text inside the tooltip, making it bold, italic etc.
