Use the keyword OVERPLOT rather than NOERASE if you want
to draw the downhill contours on top of the filled contours.

Hi Martijn
Try the following
!p.multi=[0,2,2]
contour,x,/fill,nlevels=10
!p.multi=[4,2,2]
contour,x,/downhill,nlevels=10,/noerase
It should do the trick. If I remember correctly the first element
of !p.multi contains information about the remaining plots. Setting
!p.multi=[0,2,2] is also ok.
