Why did "useOpenGL" not work?

element W.SJ

I wrote a example :

import QtCharts 2.2
import QtQuick 2.2


ChartView {
    title: "Line"
    width: 800
    height: 600
    antialiasing: true

    LineSeries {
        name: "LineSeries"

        XYPoint { x: 0; y: 0 }
        XYPoint { x: 1.1; y: 2.1 }
        XYPoint { x: 1.9; y: 3.3 }
        XYPoint { x: 2.1; y: 2.1 }
        XYPoint { x: 2.9; y: 4.9 }
        XYPoint { x: 3.4; y: 3.0 }
        XYPoint { x: 4.1; y: 3.3 }
    }
}

And got the result:

Then set "useOpenGL: true" :

import QtCharts 2.2
import QtQuick 2.2

ChartView {
    title: "Line"
    width: 800
    height: 600
    antialiasing: true

    LineSeries {
        name: "LineSeries"

        useOpenGL: true

        XYPoint { x: 0; y: 0 }
        XYPoint { x: 1.1; y: 2.1 }
        XYPoint { x: 1.9; y: 3.3 }
        XYPoint { x: 2.1; y: 2.1 }
        XYPoint { x: 2.9; y: 4.9 }
        XYPoint { x: 3.4; y: 3.0 }
        XYPoint { x: 4.1; y: 3.3 }
    }
}

and got blank result:

Is there anyone help me?

I'm getting the same issue.
Have you solved this problem yet? If true, could you share me how to fix it?
Thanks!
