jqCandlestick is a jQuery and canvas based plugin that makes it easier to create point chart, plot chart, line chart, column chart, bar chart, and candlestick chart.

Basic Usage:

1. Include the latest version of jQuery library and jqCandlestick plugin on the web page.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery.jqcandlestick.min.js"></script>

2. Create a container for a chart.

<div id="demo"></div>

3. The basic CSS styles for the chart.

.jqcandlestick-container {
position: relative;
cursor: none;
}
.jqcandlestick-canvas {
position: absolute;
display: block;
height: 100%;
width: 100%;
}

4. Generate random data in the javascript only for example.

<script type="text/javascript">

var data = [];

var time = new Date('2013-12-01 12:00').valueOf();

var h = Math.floor(Math.random() * 100);
var l = h - Math.floor(Math.random() * 20);
var o = h - Math.floor(Math.random() * (h - l));
var c = h - Math.floor(Math.random() * (h - l));

var v = Math.floor(Math.random() * 1000);

for (var i = 0; i < 30; i++) {
  data.push([time, o, h, l, c, v]);
  h += Math.floor(Math.random() * 10 - 5);
  l = h - Math.floor(Math.random() * 20);
  o = h - Math.floor(Math.random() * (h - l));
  c = h - Math.floor(Math.random() * (h - l));
  v += Math.floor(Math.random() * 100 - 50);
  time += 30 * 60000; // Add 30 minutes
}
</script>

5. Call the plugin with options.

<script type="text/javascript">
$(function() {
$('#example-6').jqCandlestick({
data: data,
theme: 'light',
series: [{
type: 'candlestick',
color: '#00C',
