详细描述

Each series can be bound to one or more horizontal and vertical axes, but mixing axis types that would result in different domains is not supported, such as specifying QValueAxis and QLogValueAxis on the same orientation.

The properties and visibility of various axis elements, such as axis line, title, labels, grid lines, and shades, can be individually controlled.
