QT Charts dragable

[ht1723]

Hi,
I have a question regarding QT Qml and QT Charts.
I want to create a interface, where the User can add Control Elements and choose a time where the Control should be activated.
It should be possible to drag a point in the chart, for example from the Point 40/0 to the Point 50/0 (see code comments below), is there a way to do this with Qt Charts? In the Chart Example scatterinteractions i found a solution to mark scatter points, but i want also to be able to move the marked Points, and use the x values of the moved point to configure my time control.

Thank you for your help!

import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Layouts 1.3
import QtCharts 2.0

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Diagram")
    ChartView {
        title: "Diag"
        anchors.fill: parent
        antialiasing: true

        ValueAxis {
            id: valueAxis
            min: 0
            max: 60
            tickCount: 7
            labelFormat: "%.0f"
        }
        ValueAxis {
            id: axisY
            min: 0
            max: 1.5
            tickCount: 3
            labelFormat: "%.0f"
        }

        LineSeries {
            name: "signal 1"
            axisX: valueAxis
            axisY: axisY
            XYPoint { x: 0; y: 0 }
            XYPoint { x: 10; y: 0 }
            XYPoint { x: 10; y: 1 }
            XYPoint { x: 40; y: 1 } //drag this point to 50/1
            XYPoint { x: 40; y: 0 } //drag this point to 50/0
            XYPoint { x: 60; y: 0 }
        }
    }
}
