1. Including TEXT configuration

    Example file: TEXT01.js

    Data structure

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

    var TEXT01 = [ "TEXT01" , {
     x: -20,
     y: 0,
     textSize: 20,
     textWeight: "bold",
     textColor: "red",
     textOpacity: 1.0,
     text: "EGFR"
  }];

2. Initialize TEXT configuration with data tag : TEXT01

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

    NGCircos01 = new NGCircos(BACKGROUND01,NGCircosGenome,{ // Initialize with "BACKGROUND01" data tag

3. Source code

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