There is only one x Axis, however there can be multiple y axes.

\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
