\brief The QAbstractAxis class is used for manipulating chart's axis.
|
|
|
|
|
|
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.
|
|
|
|
|
|
Properties and visibility of various axis elements such as axis line, title, labels, grid lines,
|
|
|
and shades can be individually controlled.
