How to make Binscatter Plot transparent over Contour Lines?

I want make the Blue Contour Lines to appear on the Binscatter plot, with some amount of Transparency. These blues should be visible on the Yellow and Red boxes but not fully blue, a lightened version.

This is the relevant code:

h = binscatter(nplot,tqplot)

[Walter Roberson]

h.FaceAlpha = 0.7;    %or other transparency level, 0 being fully transparent

There are also approaches involving moving the contour plot to the top of the graphic hierarchy and then setting alpha on the contour lines. There is no documented method of setting the alpha for contour lines, but it is possible; undocumentedmatlab shows how to do it.

Thanks a lot Walter!
