Ok, here is the program:

items=['Disk stars','Diskless stars']

if(kd ne !NULL) then $
cgHistoplot,P[kd],binsize=0.5,xrange=[0.,16.],$
max_value=maxvalue,$
/fill,polycolor=['light coral']

cgHistoplot,P[kdl],binsize=0.5,/oplot,$
xrange=[0.,16.],/fill,polycolor=['royal blue']

firstPlot=cgsnapshot()

cgHistoplot,P[kdl],binsize=0.5,xrange=[0.,16.],/fill,$
max_value=maxvalue,polycolor=['royal blue']

if(kd ne !NULL) then $
cgHistoplot,P[kd],binsize=0.5,/fill,$
/oplot,xrange=[0.,16.],polycolor=['light coral']

secondPlot=cgsnapshot()

cgBlendimage, firstPlot, secondPlot, ALPHA=0.75

AL_legend,items, PSym=16,charsize=1.,/window,$
SymSize=1, Color=['light coral','royal blue'],pos=[7.,15000]

Then I got the message "A cgwindow does not exist to add a command to". But I cannot figure out which options I should use in order to have the blending and the legend.

Thank you for your attention,
Jaqueline
