Chord Canvas

This is a HTML5 build of Dynamic Chord Diagam.

Usage:

  • Include JavaScript at HTML head.
    <script src="http://commondatastorage.googleapis.com/ggshow/files/chordcanvas/chordcanvas-1-0-0.min.js"></script>
  • Creating/rendering chord instance.
    var myChord = new ChordCanvas(value, size);
    myChord.render();

Simplified method:

  • <script>new ChordCanvas("C,X,3,2,0,1,0","100").render();</script>

Customize Color:

  • var chord1 = new ChordCanvas("C,X,3,2,0,1,0","150");
    chord1.backgroundcolor = "#CCF";
    chord1.bordercolor = "";
    chord1.titlecolor = "#FFF";
    chord1.labelcolor = "#00F";
    chord1.chordcolor = "#00F";
    chord1.titlebackgroundcolor = "#00F";
    chord1.render();

Overwrite chord container display style:

  • Chord container has block display by default, you can overwrite the display style by .chord-container class selector. e.g:
    <style>
    .chord-container {
        display:inline-block;
    }
    </style>

Examples:

Source:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Chord Canvas - Example 01</title>
<style>
.chord-container {
display:inline-block;
}
</style>
<script src="http://commondatastorage.googleapis.com/ggshow/files/chordcanvas/chordcanvas-1-0-0.min.js"></script>
</head>
