    \class QChartAxis
    \brief The QChartAxis class is used for manipulating chart's axis
    and for adding optional axes to the chart.
    \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 share common X axis.
    Axis can be setup to show axis line with ticks, gird lines and shades.
