GMT绘制文献计量中的作者每年的文章发表量
在进行文献计量作图时，我们有时需要绘制作者每年发表文章的变化。之前在公众号看到一篇关于GMT绘制的方法：https://mp.weixin.qq.com/s/N3IsZBWWraVc9Kk0KmtRfg。经过个人的琢磨，我最终实现了如下的效果。
实现的代码如下：
gmtset PLOT_DEGREE_FORMAT ddd:mm:ssF
gmtset MAP_FRAME_TYPE plain
gmtset FRAM_WIDTH 0.04c
gmtset LABEL_FONT 2
gmtset LABEL_FONT_SIZE 10p
gmtset ANNOT_FONT_SIZE_PRIMARY 10p
gmtset MAP_FRAME_WIDTH 1p
gmtset MAP_ANNOT_OFFSET_PRIMARY 0.1c
set J=Cyl_stere/0/0/10c
set R=70/140/15/55
REM set J = N16c
set PS="author1.ps"

gmt makecpt -Cpolar -T0/60/1 >point.cpt
