Detailed Description

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.

Member Type Documentation

enum QAbstractAxis::AxisType
flags QAbstractAxis::AxisTypes

The type of the axis object.

ConstantValue
QAbstractAxis::AxisTypeNoAxis0x0
QAbstractAxis::AxisTypeValue0x1
QAbstractAxis::AxisTypeBarCategory0x2
QAbstractAxis::AxisTypeCategory0x4
QAbstractAxis::AxisTypeDateTime0x8
QAbstractAxis::AxisTypeLogValue0x10

The AxisTypes type is a typedef for QFlags<AxisType>. It stores an OR combination of AxisType values.
