ChartView and scrollbar

[SeeLook]

Hi
I couldn't find it in any doc.

How to make ChartView scrollable with mouse (finger) when appended data goes out of defined X axis maximum?

Have you tried to put it into Flickable {} ?

Thanks for clue, but seems like ChartView has fixed size.
I added MouseArea to handle it - it works like dragging

ChartView {
    id: chartView
    MouseArea {
        anchors.fill: parent
        property int lastX: 0
        property int lastY: 0
        onPressed: {
            lastX = mouse.x
            lastY = mouse.y
        }

        onPositionChanged: {
            if (lastX !== mouse.x) {
                chartView.scrollRight(lastX - mouse.x)
                lastX = mouse.x
            }
            if (lastY !== mouse.y) {
                chartView.scrollDown(lastY - mouse.y)
                lastY = mouse.y
            }
        }
    }
}

Have you tried qchart with graphicsview framework?

Yes, in another project.
QGraphicsView lays a top of QAbstaractScrollArea, so scroll bars appears there out of a box. But it requires a few lines of code to add scrolling by drag a scene.
This time I needed QML way.
