1. Including LEGEND configuration

    Example file: LEGEND01.js

    Data structure

    Users should prepare the input data in the following format (separated by tabs).

    var LEGEND1 = [ "LEGEND1" , {
   x: 300,
   y: -230,
   title: " ",
   titleSize: 16,
   titleWeight: "bold",
   GapBetweenGraphicText:5,
   GapBetweenLines:20
   } , [
      {type: "circle", color:"#1E77B4",opacity:"1.0",circleSize:"8",text: "C.CK", textSize: "14",textWeight:"normal"},
      {type: "circle", color:"#AEC7E8",opacity:"1.0",circleSize:"8",text: "C.NPK", textSize: "14",textWeight:"normal"},
      {type: "circle", color:"#FF7F0B",opacity:"1.0",circleSize:"8",text: "GC.CK", textSize: "14",textWeight:"normal"},
      {type: "circle", color:"#FFBB78",opacity:"1.0",circleSize:"8",text: "GC.NPK", textSize: "14",textWeight:"normal"},
      .....
      {type: "circle", color:"#BCBC22",opacity:"1.0",circleSize:"8",text: "Verrucomicrobia", textSize: "14",textWeight:"normal"},
      {type: "circle", color:"#DADB8D",opacity:"1.0",circleSize:"8",text: "Ascomycota", textSize: "14",textWeight:"normal"},
      {type: "circle", color:"#19BDCF",opacity:"1.0",circleSize:"8",text: "Basidiomycota", textSize: "14",textWeight:"normal"},
      {type: "circle", color:"#9ED9E5",opacity:"1.0",circleSize:"8",text: "Zygomycota", textSize: "14",textWeight:"normal"},
   ]];

2. Initialize LEGEND configuration with data tag : LEGEND01

    Prepare a <div> tag with “example” id to set the picture position your will draw in html, e.g.:

    NGCircos01 = new NGCircos(LEGEND01,NGCircosGenome,{ // Initialize with "LEGEND01" data tag

3. Source code

    When step 1 and 2 are finished, the configuration for NGCircos: 

    <button class="svg-action-btn download-img" style="height: 18px;line-height: 18px;padding: 0 11px;background: #FFFFFF;border: 1px #D9D9D9 solid;border-radius: 3px;display: inline-block;font-size: 12px;outline: none;color: black">Download png ↓</button>
<a href="javascript:(function () { var e = document.createElement('script');if (window.location.protocol === 'https:') { e.setAttribute('src', './lib/svg-crowbar.js'); } else { e.setAttribute('src', './lib/svg-crowbar.js'); } e.setAttribute('class', 'svg-crowbar'); document.body.appendChild(e); })();" style="height: 18px;line-height: 18px;padding: 0 11px;background: #FFFFFF;border: 1px #D9D9D9 solid;border-radius: 3px;display: inline-block;font-size: 12px;outline: none;color: black" >Download svg ↓</a>

            <div class="row">
                <div class="col-lg-12">
