				Flotcharts is a library used for drawing different kinds of charts.
			</li>
			
			<li>
				For more info about it, please see <a href="http://www.flotcharts.org/">www.flotcharts.org</a>
			</li>
			
			<li>
				To use it, you should include:
				<br />
				<code>assets/js/flot/jquery.flot.js</code>
				<br />
				<code>assets/js/flot/jquery.flot.resize.js</code> (to make it responsive)
			</li>
			
			<li>
				I have only included the basic files but
				it has many extra modules for different types of charts which you can download from its page.
			</li>
			
			<li>
				IE8 support is provided via <b>excanvas</b>.
				<br />
				You can use the following code to include excanvas for IE8 and below:
<pre data-language="html">
<!--[if lte IE 8]>
 <script src="path/to/assets/js/excanvas.js"></script>
<![endif]-->
 &lt;script src="path/to/assets/js/flotcharts.js"&gt;&lt;/script&gt;

			A basic pie chart example would be like this:
<pre data-language="javascript">
var data = [
    { label: "social networks",  data: 38.7, color: "#68BC31"},
    { label: "search engines",  data: 24.5, color: "#2091CF"},
    { label: "ad campaigns",  data: 8.2, color: "#AF4E96"},
    { label: "direct traffic",  data: 18.6, color: "#DA5430"},
    { label: "other",  data: 10, color: "#FEE074"}
]

$('#piechart-placeholder').css({'width':'90%' , 'min-height':'150px'});
var my_chart = $.plot('#piechart-placeholder', data, {
 series: {
  pie: {
    show: true,
    tilt: 0.8,
    highlight: {
        opacity: 0.25
    },
    stroke: {
        color: '#fff',
        width: 2
    },
    startAngle: 2
  }
 },
 legend: {
   show: true,
   position: position || "ne", 
   labelBoxBorderColor: null,
   margin:[-30,15] //some offsetting
 },
 grid: {
   hoverable: true,
   clickable: true
 }
})
</pre>

Chart tooltip example:
<pre data-language="javascript">
//pie chart tooltip example
//create the tooltip once
var $tooltip = $("&lt;div class='tooltip top in'>&lt;div class='tooltip-inner'>&lt;/div>&lt;/div>").hide().appendTo('body');

var lastIndex = null;
$('#piechart-placeholder').on('plothover', function (event, pos, item) {
   if(item) {
      if (lastIndex != item.seriesIndex) {
           lastIndex = item.seriesIndex;
           var tooltip_text = item.series['label'] + " : " + item.series['percent']+'%';
           $tooltip.show().children(0).text(tooltip_text);
           //or
		   //$tooltip.find('.tooltip-inner').text(tooltip_text);
       }
       $tooltip.css({top:pos.pageY + 10, left:pos.pageX + 10});
   } else {
      $tooltip.hide();
      lastIndex = null;
   }
 });

</pre>
			</li>
			
			
			<li>
			Another basic example:
<pre data-language="javascript">
 var d1 = [];//dataset 1 (random data)
 for (var i = 0; i < Math.PI * 2; i += 0.5) {
   d1.push([i, Math.sin(i)]);
 }
 var d2 = [];//dataset 2 (random data)
 for (var i = 0; i < Math.PI * 2; i += 0.5) {
    d2.push([i, Math.cos(i)]);
 }

 //we put the chart inside #sales-charts element
 $('#sales-charts').css({'width':'100%' , 'height':'220px'});
 var my_chart = $.plot("#sales-charts", [
    { label: "Domains", data: d1 },
    { label: "Hosting", data: d2 }
 ], {
    hoverable: true,
    shadowSize: 0,
    series: {
        lines: { show: true },
        points: { show: true }
    },
    xaxis: {
        tickLength: 0
    },
    yaxis: {
        ticks: 10,
        min: -2,
        max: 2,
        tickDecimals: 3
    },
    grid: {
        backgroundColor: { colors: [ "#fff", "#fff" ] },
        borderWidth: 1,
        borderColor:'#555'
    }
 });
</pre>

				Please note that when drawing charts inside a container which is initially hidden,
				such as a hidden tab pane or a modal dialog, 
				dimensions are unknown and charts may not be drawn properly.
				<br />
				You should try drawing/redrawing your chart when the container is displayed:
<pre data-language="javascript">
$('#my-modal).on('shown.bs.modal', function() {
  my_chart.draw();
});

$('#myTab a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
   //if( $(e.target).is('#my-desired-tab') ) my_chart.draw();
})
</pre>
