QML ChartView how to remove axis and scale?

[MikhailG]

Hello! I encounter some difficulties with managing to remove axis and scale from this view. Red arrows are pointing out what I want to remove. In documentation I did not find any relevant information to this problem. Please any piece of advice would be great! Thank you.!

I use OSCILLOSCOPE example.

ChartView {
    id: chartView
    animationOptions: ChartView.NoAnimation
    theme: ChartView.ChartThemeDark
    legend.visible: false

    property bool openGL: true
    onOpenGLChanged: {
        series("signal 1").useOpenGL = openGL;
        series("signal 2").useOpenGL = openGL;
    }

    ValueAxis {
        id: axisY1
        min: -1
        max: 4

        color: "transparent"
    }

    ValueAxis {
        id: axisX
        min: 0
        max: 1024

        color: "transparent"
    }

    LineSeries {
        id: lineSeries1
        name: "signal 1"
        axisX: axisX
        axisY: axisY1
        useOpenGL: chartView.openGL
    }

    Timer {
        id: refreshTimer
        interval: 1 / 60 * 1000 // 60 Hz
        running: true
        repeat: true
        onTriggered: {
            dataSource.update(chartView.series(0));
            dataSource.update(chartView.series(1));
        }
    }

    function changeSeriesType(type) {
        chartView.removeAllSeries();

        if (type == "line") {
            var series1 = chartView.createSeries(ChartView.SeriesTypeLine, "signal 1",
                                                 axisX, axisY1);
            series1.useOpenGL = chartView.openGL

        } else {
            var series1 = chartView.createSeries(ChartView.SeriesTypeScatter, "signal 1",
                                                 axisX, axisY1);
            series1.markerSize = 2;
            series1.borderColor = "transparent";
            series1.useOpenGL = chartView.openGL
        }
    }

    function createAxis(min, max) {
        // The following creates a ValueAxis object that can be then set as a x or y axis for a series
        return Qt.createQmlObject("import QtQuick 2.0; import QtCharts 2.0; ValueAxis { min: "
                                  + min + "; max: " + max + " }", chartView);
    }

    function setAnimations(enabled) {
        if (enabled)
            chartView.animationOptions = ChartView.SeriesAnimations;
        else
            chartView.animationOptions = ChartView.NoAnimation;
    }

    function changeRefreshRate(rate) {
        refreshTimer.interval = 1 / Number(rate) * 1000;
    }

Somehow I managed to solve it. Just had to check official examples one more time.
To remove labels and a grid (scale).

ValueAxis {
      labelsVisible: false
      gridVisible:false
}
