  geom_point(data = JZKJ$"300566.SZ.Close"[sellpoint, ],aes(x=index(JZKJ$"300566.SZ.Close"[sellpoint, ]),y="300566.SZ.Close",color="sell"))+geom_text(data = JZKJ$"300566.SZ.Close"[sellpoint, ],aes(x=index(JZKJ$"300566.SZ.Close"[sellpoint, ]),y="300566.SZ.Close",label=rep("sell",length(JZKJ$"300566.SZ.Close"[sellpoint, ]))))
