set and unset label for multiplot?

[mlt]

I have a multiplot containing two plots:

# Label the controlpoints
y_offset = 0.5
set label "X_0" at 8,4+y_offset
set label "X_1" at 12,6+y_offset
set label "X_2" at 11,11+y_offset

set multiplot layout 1, 2
set title "pic" font "Helvetica,20"
plot "data1.dat" using 1:2 w points pointtype 6 linecolor rgb "blue", \
"data2.dat" using 1:2 ls 2

set label "X_3" at 5,12+y_offset
set label "X_4" at 2,9+y_offset
set label "X_5" at 3,6+y_offset

set title "pic2" font "Helvetica,20"
plot "data3" using 2:3 w points pointtype 6 linecolor rgb "blue", \
"data4.dat" using 1:2 ls 2

unset multiplot

I would like to make the label X_3-X_5 to only appear on the second plot,
but all labels appear. Is there some way around this?

I'm surprised you ask --- you wrote the answer yourself, right there in
the subject line. Or what did you think "unset label" was for?

I think another way to go about this would be:

set multiplot layout 1, 2

set label 1 "X_0" at 8,4+y_offset
set label 2 "X_1" at 12,6+y_offset
set label 3 "X_2" at 11,11+y_offset

set title "pic" font "Helvetica,20"
plot "data1.dat" using 1:2 w points pointtype 6 linecolor rgb "blue",
\
"data2.dat" using 1:2 ls 2

set label 1 "X_3" at 5,12+y_offset
set label 2 "X_4" at 2,9+y_offset
set label 3 "X_5" at 3,6+y_offset
