Send to Back in SetDrawEnv

I am having trouble with what should be a simple task.
I have a graph, I want to draw a filled rectangle to highlight a certain region of the graph, having the rectangle behind the trace.
Using SetDrawEnv I can successfully draw the rectangle on the graph.
I seem to be unable to actually change the layer order to get the rectangle behind the trace.
I have of course tried using the "Send to Back" button, but to no avail.
How it this accomplished?
Send to Back will send a draw object behind other objects in the same draw layer. You need to put the rectangle into a different draw layer. Hold down the Option key (Macintosh) or Alt key (Windows) and click on the environment tool button (the one with the tree icon). You will see a menu of draw layers. You probably want User Back.

Thanks for the tip.
It seems that the trick is to set the draw layer before actually drawing anything.
Simply drawing in the default layer still proved to not let me change the order even when following your suggestion.
Using "

SetDrawLayer UserBack" before actually drawing gives the desired result.
Again, I knew it was simple, I was just missing it.
Thanks for the help.

Right- I should have been clearer. Existing draw objects stay in the layer where you drew them. You can move them by selecting, cutting, changing the layer and pasting.
