1. Including BACKGROUND configuration

Example file: BACKGROUND01.js

Data structure

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

var BACKGROUND01 = [ "BACKGROUND01" , {
  BginnerRadius: 230,
  BgouterRadius: 200,
  BgFillColor: "#F2F2F2",
  BgborderColor : "#000",
  BgborderSize : 0.3,
  axisShow: "true",
  axisWidth: 0.1,
  axisColor: "#000",
  axisNum: 8
}];
var BACKGROUND02 = [ "BACKGROUND02" , {
  BginnerRadius: 170,
  BgouterRadius: 130,
  BgFillColor: "#F2F2F2",
  BgborderColor : "#000",
  BgborderSize : 0.3,
  axisShow: "true",
  axisWidth: 0.1,
  axisColor: "#000",
  axisNum: 8
}];
var BACKGROUND03 = [ "BACKGROUND03" , {
  BginnerRadius: 100,
  BgouterRadius: 50,
  BgFillColor: "#F2F2F2",
  BgborderColor : "#000",
  BgborderSize : 0.3,
  axisShow: "false",
  axisWidth: 0.1,
  axisColor: "#000",
  axisNum: 8
}];

2. Initialize BACKGROUND configuration with data tag : BACKGROUND01, BACKGROUND02, BACKGROUND03

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

NGCircos01 = new NGCircos(BACKGROUND01,BACKGROUND02,BACKGROUND03,NGCircosGenome,{ // Initialize with "BACKGROUND01,BACKGROUND02,BACKGROUND03" 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>
