 * \brief The Q3DCategoryAxis class is used for manipulating an axis of a graph.
 * \since 1.0.0
 *
 * Q3DCategoryAxis provides an axis that can be given labels. The axis is divided into equal-sized
 * categories based on \l {Q3DBars::setDataWindow()}{data window} size.
 *
 * Grid lines are drawn between categories, if visible. Labels are drawn to positions of categories
 * if provided.
