Each series can be bound to one or more horizontal and vertical axes, but mixing axis types that would result in different domains is not supported, such as specifying QValueAxis and QLogValueAxis on the same orientation.
The properties and visibility of various axis elements, such as axis line, title, labels, grid lines, and shades, can be individually controlled.

~QAbstractAxis
()
Destructs the axis object. When the axis is added to a chart, the chart object takes ownership.
Returns the pen used to draw the grid.
注意: Getter function for property gridLinePen.
另请参阅 setGridLinePen ().
Makes the axis, shades, labels, and grid lines invisible.
Returns the brush used to draw labels.
注意: Getter function for property labelsBrush.
另请参阅 setLabelsBrush ().
返回
true
if axis labels are editable.
