\brief The QAbstractAxis class is used for manipulating chart's axis.
\mainclass
There is only one x Axis visible at the time, however there can be multiple y axes.
Each chart series can be bound to exactly one Y axis and the shared common X axis.

\qmlclass AbstractAxis QAbstractAxis
\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...
}
\endcode
