\mainclass
|
|
|
|
|
|
BarCategoriesAxis can be setup to show axis line with tick marks, grid lines and shades.
|
|
|
Categories are drawn between ticks. Note that you can use this also with lineseries too.
|
|
|
See the \l {Line and BarChart Example} {Line and BarChart Example} to learn how to do that.

\brief The Axis element is used for manipulating chart's axes.

Categories are drawn between ticks. Note that you can use this also with lineseries too.

To access BarCategoriesAxis you can use ChartView API. For example:

\code

ChartView {

}

// Add a few series...
