                 \brief The Axis element is used for manipulating chart's axes
                 There is only one x Axis visible at the time, 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...
