title: draggable chart editing - edit values of chart by drag
body: <p>I'm using amcharts and make a live edit chart like this example (jsfiddle) :  </p>
  
  <pre><code>jsfiddle.net/amcharts/9uyAf/
  </code></pre>
  
  <p>My own chart (below image) : (now I can change values by changing input values)<br>
  <img src="https://i.stack.imgur.com/XIX9u.png" alt="enter image description here"></p>
  
  <p><strong>I try</strong> to find a alternate way to edit values of chart by <strong>dragging the values of chart instead of changing values on inputs</strong> .  </p>
  
  <p><strong>Is there</strong> a example or chart library have this features ?</p>
  
  <p>tnx ;)</p>
