title: draging a point on qtcharts in qml
body: <p>I am trying to drag a point on LineSeries on qtcharts. Here is my code:</p>
  
  <pre><code>import QtQuick 2.0
  import QtCharts 2.0
  
  Item {
      anchors.fill: parent
  
      ChartView {
          title: "Two Series, Common Axes"
          anchors.fill: parent
  
          ValueAxis {
              id: axisX
              min: 0
              max: 10
              tickCount: 5
          }
  
          ValueAxis {
              id: axisY
              min: -0.5
              max: 1.5
          }
  
          LineSeries {
              id: series1
              axisX: axisX
              axisY: axisY
              onPressed: console.log("Pressed: " + point.x + ", " + point.y);   
              onReleased: console.log("Released: " + point.x + ", " + point.y);
          }
  
  
      }
      // Add data dynamically to the series
      Component.onCompleted: {
          for (var i = 0; i &lt;= 10; i++) {
              series1.append(i, Math.random());
          }
      }
  }
  </code></pre>
  
  <p>When I press a point on the Lineserie I can see x,y of the point I have pressed and released in the console. Both are the same though, so I cannot see the place where it released. I'd like to drag a point to another place, so if I press a point it follows the (mouse/finger on touch screen) pointer until I release on the graph. Anyone can help a bit where to start and which properties should I use?</p>
