Projecting contour on the floor in a 3d plot
1
The contour is drawn on the top surface, I'm trying to plot the contour on the floor (A-B).
documentclass{standalone}
usepackage{pgfplots}
pgfplotsset{width=10cm, compat=1.9}
begin{document}
begin{tikzpicture} begin{axis}
[
xlabel=$A$,
ylabel=$B$,
zlabel=$f_0$,
grid=major,
]
addplot3[
surf,
opacity=0.4,
] {4*x + 5*y};
addplot3 [
contour gnuplot, samples=21]
{4*x + 5*y};
end{axis} end{tikzpicture}
end{document}

addplot3 [ contour gnuplot, samples=21,z filter/.code={defpgfmathresult{-49.9}}] {4*x + 5*y};? (Or any value you want instead of-49.9.)

I tried that, this changes the contour height, but it's not on the floor perfectly.

@TahaMagdy I just setzminto-55and added the contour a tiny bit above (such that it does not clipped away).
