| \brief The Axis element is used for manipulating chart's axes | ||||
| 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 | ||||
| */ | ||||
| /*! | ||||
| \property QValuesAxis::min | ||||
| Defines the minimum value on the axis. | ||||
| */ | ||||
| /*! | ||||
| \qmlproperty real Axis::min | ||||
| Defines the minimum value on the axis. | ||||
| */ | ||||
| /*! | ||||
| \property QValuesAxis::max | ||||
| Defines the maximum value on the axis. | ||||
| */ | ||||
| /*! | ||||
| \qmlproperty real Axis::max | ||||
| Defines the maximum value on the axis. | ||||
| */ | ||||
| /*! | ||||
| \fn void QValuesAxis::minChanged(qreal min) | ||||
| Axis emits signal when \a min of axis has changed. | ||||

| /*! | ||||
| \fn void QValuesAxis::maxChanged(qreal max) | ||||
| Axis emits signal when \a max of axis has changed. | ||||
| */ | ||||
| /*! | ||||
| \fn void QValuesAxis::rangeChanged(qreal min, qreal max) | ||||
| Axis emits signal when \a min or \a max of axis has changed. | ||||
