Surface in 2d, or plane region
I often need to draw an "elemental region" of the plane, that is a set of the form
a <= x <= b
f(x) <= y <= g(x)
I can do that with the surface command in 3D, but it seems that command is not implemented in the 2D view (why?)
As a workaround I draw it in the xy plane in 3D, but it is annoying that I have to manually "rotate" the xy axis so that they don't look ugly like this
Any idea how can I improve that? Thanks in advance.
