Question:axes on 2D plot

Jsoh 12 Maple
I would like to have labeled axes on all four sides of my 2D plot. I can get them on the right and bottom using axes=normal. I can also get them on the left and bottom using axes=boxed or axes=framed. But I can't get the axes on the top of the plot to show up. Any suggestions?
