Placing a transparent gray rectangle region on a graph

The plotting is going well, however I need to place rectangle regions that are say grey yet transparent so that none of the graphical elements are blocked. How do I do this. Please be specific. I have tried the layout and the objects are opaque.

The rectangle regions are specified by a pair of opposite corner coordinates. Therefore, there is no other data.

Thanks

Try
SetDrawLayer /W=GraphName UserBack

before drawing your rectangle region. You should be able to see the graph's contents that are in front of this layer.

Transparent fill colors are not yet supported.

I suggest placing the rectangle into a layer below the items you do not wish to cover up.

To draw manually into a layer, option (alt) click on the environment icon (tree symbol) in the tools.

Using the beta of 6.1, you can specify a transparent background for fill patterns (not solid colors):

Draw patterns can be transparent using "magic" white background color value of
(65534,65534,65534). Does not work with emf or wmf export.
