()), an x-label (set via set_xlabel()), and a y-label set via set_ylabel()). The Axes class and its member functions are the primary entry point to working with the OOP interface, and have most of the plotting methods defined on them (e.g. ax.plot(), shown above, uses the...

Axis实例的set_xlabel和set_ylabel方法可以设置轴标签。这两个函数可以接受其他参数用于设置文本属性。可选参数labelpad可以设置轴与标签之间的距离(以磅为单位)。set_title方法的loc参数可以赋值为’left’、‘centered’、‘right’,用于设置标题的对齐方式。
