I just ran into this with dates and I finally had to just use "which" on the
input data with an expression for the xlim values, d[which( d>xi)&(d<xf)) ]
for example. The plot documentation seems to refer to use of raw data range
instead of xlim for figuring label params. Is there an implemented option
to change this?
