[Tex/LaTex] Draw a surface using Tikz

graphicspgfplotsplottikz-pgf

I am very new to tikz and I would like to draw the following picture

I attempted and here what I got

\documentclass[border=10pt]{standalone}
\usepackage{pgfplots}
\pgfplotsset{width=7cm,compat=1.8}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
        ]
\addplot3[
  surf,
  shader=interp,
  domain=-1:1,
  domain y=-1.3:1.3,
] 
{exp(-x^2-y^2)};
\end{axis}
\end{tikzpicture}
\end{document}

here is the picture i got but I am stuck on how to use only one color and place a plane on the top of the surface.

Any help would be greatly appreciated. Thank you for your time !

Here is something - just to get you started.

\documentclass[border=10pt]{standalone}
\usepackage{pgfplots}
\pgfplotsset{width=7cm,compat=1.8}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
        ]
\addplot3[
  surf,
  colormap/blackwhite,
  shader=interp,
  domain=-1:1,
  domain y=-1.3:1.3,
] 
{exp(-x^2-y^2)};
\addplot3[fill=magenta, opacity=0.5]
coordinates{
(-1,-1,1)
(-1,1,1)
(1,1,1)
(1,-1,1)
};
\end{axis}
\end{tikzpicture}
\end{document}

[Tex/LaTex] plotting two time series with bounds

This happens because PGFPlots only uses one "stack" per axis: You're stacking the second confidence interval on top of the first. The easiest way to fix this is probably to use the approach described in "Is there an easy way of using line thickness as error indicator in a plot?": After plotting the first confidence interval, stack the upper bound on top again, using stack dir=minus. That way, the stack will be reset to zero, and you can draw the second confidence interval in the same fashion as the first:
