\class QAbstractAxis | ||||
\brief The QAbstractAxis class is used for manipulating chart's axis. | ||||
\mainclass | ||||
There is only one x Axis, however there can be multiple y axes. | ||||
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. | ||||

\qmlclass Axis QAbstractAxis | ||||
\brief The Axis element is used for manipulating chart's axes | ||||
There is only one x Axis, however there can be multiple y axes on a ChartView. | ||||
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 | ||||
