\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.
