Graphics, Figures & Tables ⇒ Proportions messed up in animation

[Alrik]

Hi together,

I'm trying to create an animated Chi-Square Distribution from a static file with ps-tricks and animate, but the proportions are completely messed up in the animated figure. I guess there's some tiny rub in my code I'm too blind by now to find...

The static figure:

Code: Select all

\documentclass[a4paper,12pt]{article}
\usepackage{pst-func}
\usepackage{graphicx} %graphic support

\begin{document}

\psset{xunit=1cm,yunit=7.5cm,plotpoints=200}
\begin{pspicture*}(-0.9,-0.1)(12,.9)
 \rput[t]{0}(4,0.5){$f(x;k) = \frac{1}{2^{k/2}\Gamma(k/2)}x^{k/2-1}e^{-x/2}$}
 \multido{\rnue=0.5+0.5, \iblue=10+10, \rloc=0.6+-0.05}{10}{%
 \psChiIIDist[linewidth=1pt, linecolor=blue!\iblue, nue=\rnue]{0.01}{11}
 \psframe*[linecolor=white,framearc=0.1](8,0.1)(8,0.7)
 \psline[linewidth=1pt, linecolor=blue!\iblue]{-}(8,\rloc)(8.5,\rloc)
 \uput[0](8.7,\rloc){\scriptsize k = \rnue}}
 \psaxes[Dy=0.1, tickstyle=bottom]{->}(0,0)(0,0)(12,.9)
\end{pspicture*}

\end{document}

The animated figure:

Code: Select all

\documentclass[a4paper,12pt]{article}
\usepackage{pst-func}
\usepackage{graphicx}
\usepackage{animate}

\begin{document}
%-------------------- write timeline file ---------------------%
\newwrite\TimeLineFile
\immediate\openout\TimeLineFile=chi.txt
\immediate\write\TimeLineFile{::0x0}
\multido{\i=1+1}{10}{\immediate\write\TimeLineFile{::\i}}
\immediate\closeout\TimeLineFile
%------------------- assemble animation ------------------------%
\psset{xunit=1cm, yunit=7.5cm, plotpoints=200}
\begin{animateinline}[controls, 
                      buttonsize=1em,
                      timeline=chi.txt,
                      begin={\begin{pspicture}(-0.9,-0.1)(12,.9)},
                      end={\end{pspicture}}]{6}
\psaxes[Dy=0.1, tickstyle=bottom]{->}(0,0)(0,0)(12,.9)
\newframe
\multiframe{10}{rnue=0.5+0.5, iblue=10+10, rloc=0.6+-0.05}{%
\psChiIIDist[linewidth=1pt, linecolor=blue!\iblue, nue=\rnue]{0.01}{11}
\psline[linewidth=1pt, linecolor=blue!\iblue]{-}(8,\rloc)(8.5,\rloc)
\psframe*[linecolor=white,framearc=0.1](8,0.1)(8,0.7)
\uput[0](8.7,\rloc){\scriptsize k = \rnue}}
\end{animateinline}

\end{document}

Thanks for any help,

Alrik

P.S.: I use the output profile LaTeX=>PS=>PDF under Windows Vista with MikTex 2.7 and TeXnic Center 1 Beta 7.50.

I have no problem with this slightly modified example

Hi Herbert,

thank you very much. The problem is not so much the animation itself as the aspect ratio of the figure. I've attached the 2 pdf.files that are produced when I run my code. Notice the messed-up aspect (axes scales) although I use exactly the same coordinate specifications in both figures. The same distortion happened when I ran your code.

Best wishes, Alrik

[CrazyHorse]

understood ...
attached my pdf. I suppose a problem in your config.ps and
the paper format. try to find it with

kpsewhich config.ps

and look for the paper descriptions

Hallo Herbert,

thanks again, it works now although all I did after all was to re-install ghostscript...maybe it has automatically re-set the paper size definitions.

Best wishes,

Alrik

Hallo.
I have now the same problem, the proportions are messed up. what can I do?
I didn't understand the solution of crazyHorse.

[Alrik]

Hi jonysatie,

in the end I had the same problem again. My solution now is to simply use LaTeX => PS and open the file with Acrobat Distiller. That works strangely enough. Using LaTeX => PS => PDF won't.

[jonysatie]

Ok, Thank you. I hope anyone can find a possible solution to this thread in animate package.
Best regards.

Please, make sure your editor doesn't call DVIPS with option -Ppdf when going the LaTeX => PS => PDF route. See `Bugs' section in the animate documentation for explanation.

Hi alex,

perfect! It works now. Thanks a lot for your help.

Best wishes, Alrik
