\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 BarCategoriesAxis you can use ChartView API. For example:

\code

|

ChartView {

BarCategoriesAxis {
|
|
|
id: categoryAxis
|
|

}

// Add a few series...
