I'm not sure what your question is, but if it's that the plotting
characters in the legend does not match the ones in the plot, the
simplest way to fix that is

xyplot(LOAD_1 ~ mins, data=upt, type=c('g','p','r'), scales=lst,
groups=hr, auto.key=list(space = "left"),
       par.settings = simpleTheme(pch=1:2))
