Extension to "Overplotting Data on !P.MULTI Plots" [message #35727]

After overplotting data on !P.MULTI Plots it is sometimes necessary to
plot the axis, titles etc again to have the axis (which is mostly
black) drawn over your data lines (which are often colored).
But plot, data, /noerase, /nodata jumps to the next plot window. For
that,
!p.multi(0)=!p.multi(0)+1 helps, as you can see in the following code.

I am posting, because I met several people who were confused about
that.

Example code for "nodata noerase plot after overplotting Data on
!P.MULTI Plots":

!P.MULTI= [0, 2, 2]

p_sav=replicate(!p, 4)
x_sav=replicate(!x, 4)
y_sav=replicate(!y, 4)

for i=0, 3 do begin
plot, [0,1], [0, 1], title=string(i), /nodata
p_sav(i)=!p & x_sav(i)=!x & y_sav(i)=!y
end

for i=0, 3 do begin
!p=p_sav(i) & !x=x_sav(i) & !y=y_sav(i)
oplot, [.5], [.5], psym=i
end

for i=0, 3 do begin
!p=p_sav(i) & !x=x_sav(i) & !y=y_sav(i)
!p.multi(0)=!p.multi(0)+1
plot, [0,1], [0, 1], title=string(i), /nodata, /noerase
end
