I think the problem here is in using the /normal keyword in multiple
plots.

Doing this:
plot,findgen(10)
xyouts,.1,.1,char,/normal

places char in the lower left hand part of the screen, regardless of
whether you're using multiple plots or not, which is no good.

I wrote the following code to overcome this problem:

Mark

;
pro
sub_xyouts,xx0,yy0,char,charsize=charsize,xdata=xdata,ydata= ydata,color=color,align=align

;xx0 and yy0 are usually normal coordinates, eg, fraction of the
current area of the plot
;setting the xdata or ydata keywords converts xx0 and yy0 from data to
normal coordinates

xx=xx0
yy=yy0

delx=!x.window(1)-!x.window(0)
dely=!y.window(1)-!y.window(0)

if keyword_set(ydata) then yy=(yy-!y.crange(0))/(!y.crange(1)-!
y.crange(0))
if keyword_set(xdata) then xx=(xx-!x.crange(0))/(!x.crange(1)-!
x.crange(0))
col=0
if keyword_set(color) then col=color

xx=!x.window(0)+xx*delx+.02*delx
yy=!y.window(0)+yy*dely+.02*dely

csize=.8
if (keyword_set(charsize)) then csize=charsize

col=0
if keyword_set(color) then col=color

aline=0.
if keyword_set(align) then aline=align
xyouts,xx,yy,char,charsize=csize,/normal,color=col,align=ali ne

return
end
