    \brief The QAbstractAxis class is used for manipulating chart's axis.
    \mainclass

    There is only one x Axis, however there can be multiple y axes.
    Each chart series can be bound to exactly one Y axis and the shared common X axis.
    Axis can be setup to show axis line with tick marks, grid lines and shades.

    \qmlclass Axis QAbstractAxis
    \brief The Axis element is used for manipulating chart's axes

    There is only one x Axis, however there can be multiple y axes on a ChartView.
    Each chart series can be bound to exactly one Y axis and the shared common X axis.
    Axis can be setup to show axis line with tick marks, grid lines and shades.

    To access Axes you can use ChartView API. For example:
    \code
        ChartView {
            axisX.min: 0
            axisX.max: 3
            axisX.ticksCount: 4
            axisY.min: 0
            axisY.max: 4
            // Add a few series...
        }
    \endcode
