大神们，想请教个问题，
现在想画图，实现下图中的黄色部分的label，
下图是正确的 要画出的图的样子：
现在遇到一点问题，问题在于，要让从day1(就是横轴的D1)开始到D29 是 period 1, D43到D72 是 period 2, D85 和 D127是follow-up period,
我现在画出来的图（下图），这个对应关系不太对，我用粉色圈出来了，比如 D1 之前的，Scr那块不应该是period1, D29到D43那块应该是空的才对，D43应该算period 2, D71后面应该是follow-up period....
请大神们帮着看看是什么问题导致的，要怎么解决，拜谢！！！！！！！！！！
我dummy了点数据集，如下：
data dummy;
length avis aper $50;
trtn = 1; legend='0.1A-B';avisitn = -1; avisitn_ = . ;avis = 'Scr'; aper = ''; median = 34;lclm=.;uclm=.;

trtn = 1; legend='0.1A-B'; avisitn = 0; avisitn_ = 0 ;avis = 'D1'; aper = 'Treatment Period 1'; median = 33;lclm=.;uclm=.;
