详细描述

QCategory3DAxis provides an axis that can be given labels. The axis is divided into equal-sized categories based on the data window size defined by setting the axis range.

Grid lines are drawn between categories, if visible. Labels are drawn to positions of categories if provided.

特性文档编制

labels : QStringList

This property holds the labels for the axis applied to categories.

If there are fewer labels than categories, the remaining ones do not have a label. If category labels are not defined explicitly, labels are generated from the data row (or column) labels of the primary series of the graph.
