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 */ /*! \property QAbstractAxis::labelsVisible Defines if axis labels are visible. */ /*! \qmlproperty bool Axis::labelsVisible Defines if axis labels are visible. */ /*! \property QAbstractAxis::min Defines the minimum value on the axis. */ /*! \qmlproperty real Axis::min Defines the minimum value on the axis. */ /*! \property QAbstractAxis::max Defines the maximum value on the axis. */ /*! \qmlproperty real Axis::max Defines the maximum value on the axis. */ /*! \property QAbstractAxis::visible The visibility of the axis. */ /*! \qmlproperty bool Axis::visible The visibility of the axis. */ /*! \property QAbstractAxis::gridVisible The visibility of the grid lines. */ /*! \qmlproperty bool Axis::gridVisible The visibility of the grid lines. */ /*! \property QAbstractAxis::color The color of the axis and ticks. */ /*! \qmlproperty color Axis::color The color of the axis and ticks. */ /*! \property QAxis::labelsFont The font of the axis labels. */ /*! \qmlproperty Font Axis::labelsFont The font of the axis labels.
