第66-71 行则是自定义 y 轴的刻度比例范围,由于,较早年份的数据较为集中,使图表绘制集中在一块,影响美观,特经此过程进行设置,而这也是 matplotlib 3.1 版本新添加的内容。 第53 行使用 ax.axvline() 为动态图表添加一条推进线。 第54-64 行则是对图表刻度、轴脊等 属性进设置。 第75 行采用ax.yaxis....
使用matplotlib.pyplot.scatter或面向对象的方法Axes.scatter绘制散点图。通常只需要绘制最后一个数据点，因此x和y参数设置为数据的最后一个元素。设置散点的颜色color、边框颜色edgecolor、大小s和线宽lw等属性。使用zorder属性确保散点图绘制在折线图之上。添加文本：可添加国家名或指标名称等文本信息，使用ma...
