Hi guys , i'm trying to make a 3D plot with the axes at the center, but when i do it i can see through the Plot, does anyone knows how to change it?
Plot3D[{2 (x - y)/(1 + x^2 + y^2)}, {x, -a, a}, {y, -a, a},
AxesOrigin -> {0, 0, 0}, AxesStyle -> Opacity[1],
AxesEdge -> {None, Automatic, None}, ColorFunction -> "Rainbow",
Boxed -> False, Background -> Black, MeshFunctions -> {#3 &},
Mesh -> 6, MeshStyle -> {Blue}]
Thanks in advance
:D
