title: chart.js plugin for making waterfall charts
body: <p>I want to create a chart.js plugin to create waterfall charts.</p>
  
  <p>I am new to working with chart.js. I was thinking to extend the bar-chart to create a waterfall chart.</p>
  
  <p>The draw function in the bar chart controller is as follows:</p>
  
  <pre><code>draw: function(ease) {
              var me = this;
              var easingDecimal = ease || 1;
              helpers.each(me.getMeta().data, function(rectangle, index) {
                  var d = me.getDataset().data[index];
                  if (d !== null &amp;&amp; d !== undefined &amp;&amp; !isNaN(d)) {
                      rectangle.transition(easingDecimal).draw();
                  }
              }, me);
          },
  </code></pre>
