MATLAB: Is it possible to make the fill of area under the curve using area() to be translucent or shaded

area under the curvecolour

I am trying to plot 3 similar curves on top of each other with area(), however as the fill is set to block colours you can olny see the one plotted last/biggest one. Is it possible to make the fill shaded or transluscent so they are all visible at once?
Any help would be great!
Thanks.
