Hi,
thanks for the reply. I see you are using the ngrid option. I want to
get a surface-plot without any x or y lines.
I take the example of the pst-3dplot-doc.
Here You are using fillstyle=gradient. But it doesn't work with my example.
\documentclass[11pt]{article}
\usepackage{pst-3dplot}
\usepackage{pst-grad}
\usepackage{pstricks-add}
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{pspicture}(-6,-4)(6,5)
\psset{Alpha=10,Beta=30}
\psplotThreeD[plotstyle=curve,
drawStyle=yLines,
fillstyle=gradient,
yPlotpoints=50,xPlotpoints=50,
yPlotpoints=50,xPlotpoints=50,
linestyle=none](0,1)(0,1){x y mul}
\end{pspicture}
\begin{pspicture}(-6,-4)(6,5)
\psset{Alpha=45,Beta=15}
\psplotThreeD[
plotstyle=curve,
drawStyle=yLines,
fillstyle=gradient,
yPlotpoints=50,xPlotpoints=50,
linestyle=none](-4,4)(-4,4){
x 3 exp x y 4 exp mul add x 5 div sub 10 mul
2.729 x dup mul y dup mul add neg exp mul
2.729 x 1.225 sub dup mul y dup mul add neg exp add}
\end{pspicture}
\begin{tikzpicture}
\begin{axis}[colormap/cool] \addplot3[surf,samples=10,domain=0:1,
shader=interp]
{(x*y)/(x^2+x^2)}; \end{axis}
\end{tikzpicture}
\end{document}
I expect a picture like the tikz-picture :-)
regards
Marco
