3dplot in Beamer crop and ticks problem

Question

I'm new to pstricks, and I've been struggling with several issues using it with beamer.

So my problem is that I'm trying to show a 3D plot in a beamer frame. However, for some reason, that I can't understand the figure, is cropped. I already play by changing the values of the width and height of the resize box. How can I show the entire plot?

Also, because I'm resizing the image I want to reduce the number of ticks that appear in the axes. However, I tried the Dx,Dy,Dz options of the 3D axes but that only changes the step between the ticks, but do not reduce their number. What I'm saying is that now I get a tick for every number: 1,2,3,...,100 And if I change the Dx=10 option I get the same number of ticks but with different step: 10,20,30,...,1000. However, what I'm looking for is to obtain, for example, just ten ticks: 10,20,30,...,100, instead of getting hundred. Is there I way of doing this?

\documentclass{beamer}

% For the figures
\usepackage[pdf]{pstricks}
\usepackage{auto-pst-pdf}
\usepackage{pst-node, pst-plot, pst-circ, pst-3dplot}
\usepackage{moredefs}    

\begin{document}

\begin{frame}{3D}
\begin{center}
\resizebox{0.7\textheight}{0.7\textheight}{
\begin{pspicture}
\pstThreeDCoor[linecolor=black, IIIDticks,IIIDlabels,xMin=-20,xMax=20,yMin=-40, yMax=40,zMin=0,zMax=50]
\fileplotThreeD[linecolor=blue,plotstyle=line]{data.txt}

I could not completely address the issues using PSTricks, but if you are open to other options then the pgfplots package works incredibly well here.

It provided an excellent window for your plot by default, and has a very intuitive key=value approach, including the requested xmin, xmax, ymin, ymax, zmin, zmax, and xticks, yticks, and so much more.

I have included some options to get you started, but there are many more to play with- see the documentation for more details.

\documentclass{beamer}
\usepackage{pgfplots}

\begin{document}

\begin{frame}{3D}

\begin{center}
\begin{tikzpicture}
\begin{axis}[
% view={120}{0}, % change this line as needed
width=6cm,
xlabel=$x$,
ylabel=$y$,
zlabel={$z$},
%xmin=-100,xmax=100,ymin=-100,ymax=100,zmin=-20,zmax=20 % change this line as appropriate
xtick={-10,0,10},
title=Your title here]
\addplot3+[no marks] table[col sep=comma] {data.txt};    
\end{axis}
\end{tikzpicture}
\end{center}
\end{frame}

\end{document}

The problem is that the pspicture environment will exceed its bounds. Even though you have told it to stay within a box using resizebox.

You can use the environment \begin{pspicture*}...\end{pspicture*} which will automatically clip the picture if it goes outside of the boundaries. If you combine this with \psgrid you can do some experimentation to see what would be an appropriate viewing window.
