给坐标轴添加箭头 Adding arrows to axes
在初始坐标轴中是没有箭头指向的，所以我们要人为地添加坐标轴箭头以便美化图像。我们双击坐标轴，在【轴线和刻度线】的子项找到【箭头】，将【箭头位于末端】勾选上即可。There is no arrow pointing in the initial axes, so we have to artificially add axes arrows in order to beautify the image. We double-click on the axes, find [Arrowheads] in the [Axes and Scales] subsection, and check [Arrowheads at the end].
