Document Classes ⇒ No image - PStricks

[sveioen]

Hello all.

Trying to draw a graph, and PStrick looked good. But, I have ran into a problem.
I've installed pstricks via MikTeX package-utillity, and trying to generate a graph with this example-code from the PStricks webpage:

Code: Select all

\documentclass[a4paper,12pt]{article}
\usepackage{pstricks} 
\usepackage{pst-plot} 

\begin{document}

\begin{pspicture}(-0.25,-0.25)(8,8)
  \psgrid[gridlabels=0pt,subgriddiv=2,%
    gridcolor=lightgray,subgridcolor=lightgray]
  \psaxes[dx=1,Dx=2]{->}(0,0)(8,8)
\end{pspicture}

\end{document}

The problem is, no image is created. I've tried with several other example-code asa well and it's the same problem there. Does anyone know what the problem may be?

Thanks in advance!

Nevermind.

You cannot run your files with pdftex or pdflatex, see topic pdfoutput

In the \begin{pspicture}(x,y)(x1,y1), does this have anything to do with the actual picture you are drawing? What is the connection between (x,y)(x1,y1), and the coordinates in for example the \psaxes(x,y)(x,y) which actually draw something?

All your questions are answered by the documentation of the PSTricks package and further the pstricks-add package. So refer to these documents to get the information you need.

OK, I think I got it. Thanks.

And another question

Trying to make a histogram. Everything is going fine, except that I want the ticks to be on the same side as the labels. So I add the tickstyle=bottom, but it does not have any effect. I looked in code-examples, and I cant see anything wrong.

Code: Select all

\begin{pspicture}(0,0)(9,6)

\psset{yunit=1mm}
\psaxes[Dy=10,dy=1cm,Ox=-1,tickstyle=bottom,showorigin=false]{-|}(0,0)(0,0)(7,70)
\psline(0.7,0)(0.7,56)(1.3,56)(1.3,0)
\psline(1.7,0)(1.7,25)(2.3,25)(2.3,0)
\psline(2.7,0)(2.7,16)(3.3,16)(3.3,0)
\psline(3.7,0)(3.7,2)(4.3,2)(4.3,0)
\psline(4.7,0)(4.7,0)(5.3,0)(5.3,0)
\psline(5.7,0)(5.7,1)(6.3,1)(6.3,0)

\end{pspicture}

You have to add another option to the \psaxes command.

Code: Select all

\psaxes[Dy=10,dy=1cm,Ox=-1,showorigin=false,ticksize=-5pt 0]{-|}(0,0)(7,70)

The ticksize option overrides tickstyle. This is also described in Section 19.8 (ticksize, xticksize, yticksize) of the pstricks-add manual.

Worked perfectly. Thank you localghost!

I think the manual which is linked to from PStricks-website is outdated (http://cgm.cs.mcgill.ca/~msuder/latex/pstricks.pdf, thats the manual I read..). It said nothing about the tickstyle-option being removed. Sorry!

[localghost]

If you followed the link i gave you above, it would have lead you to the pstricks-add manual. The pstricks package itself is the base of all other pst-xxx packages and is rather old. But its manual is far away from being outdated. The pstricks-add package contains bug fixes and enhancements to the original. I also wrote in my last post that the ticksize option is explained in the pstricks-add manual.

Does anyone know how this expression (Poisson distribution) is expressed with RPN? (need it in RPN form to plot in PStricks)

[url]http://www.matematikk.net/cgi-bin/mimetex.cgi?F(x)%20=%20\frac{e^{-0.68}*0.68^{x}}{x!}[/url]

F(x) = \frac{e^{-0.68}*0.68^{x}}{x!}




And by the way, this forum should really have TeX support

Take a look at the documentation of the pst-func package (Section 6.3 - Poisson Distribution, p. 24ff).
