# Kan jeg bruge pstricks-pakken i Overleaf?

## Introduktion

Historisk set var en af de nemmeste måder at bruge PSTricks på Overleaf via XeLaTeX-kompileren—dvs., [sæt dit projekts kompilator til XeLaTeX](/latex/da/vidensbase/026-changing-compiler.md). I september 2021 meddelte udvikleren af PSTricks [meddelte](https://tug.org/pipermail/pstricks/2021/011321.html) at LuaLaTeX nu kunne bruges til at kompilere dokumenter, der indeholder PSTricks-kode—hvilket gav brugerne endnu en praktisk løsning.

Som beskrevet på [PSTricks-websiden](https://tug.org/PSTricks/main.cgi?file=pdf/pdfoutput#lualatex), kan LuaLaTeX tage lang tid om at kompilere ekstremt komplekse PSTricks-eksempler, især dem der kræver omfattende beregninger. LuaLaTeX's forlængede kompileringstid kan af og til udløse en [Overleaf-kompileringstimeout](/latex/da/vidensbase/038-fixing-and-preventing-compile-timeouts.md#what-is-a-e2809ccompile-timeoute2809d3f).

## Eksempler

Følgende eksempler kan alle åbnes direkte i Overleaf og bruger XeLaTeX-kompileren; du kan skifte til LuaLaTeX, når koden åbnes i Overleaf. Alle eksempler blev oprindeligt kun offentliggjort i [Overleaf Gallery](#overleaf-gallery-links) men gengives nu her for at vise PSTricks-kode i denne artikels tekst. De stammer (er gengivet) fra siden `http://www.thelazymathematician.com/p/pstricks-examples.html` som på skrivetidspunktet ikke længere synes at være tilgængelig.

* **TIP**: Besøg [PSTricks-galleriet](https://tug.org/PSTricks/main.cgi?file=examples-list) for mange flere eksempler, du kan prøve i Overleaf.

### Eksempel 1: Plotning af punkter

```latex

\documentclass[11pt]{article}
\usepackage{pst-all}	%indlæs pstricks-pakken
\begin{document}
\begin{pspicture}(-1,-1)(5,5)
\psaxes{->}(0,0)(-0.5,-0.5)(4.5,4.5)[$x$,0][$y$, 90]	%opretter akser
\psdot(2,1)	%plotter punktet (2,1)
\uput[0](2,1){$A$}	%navngiver punktet (2,1) som A
\end{pspicture}
\end{document}
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/da/sporgsmal-og-svar/06-can-i-use-the-pstricks-package-on-overleaf.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
