Graphics, Figures & Tables ⇒ Direkted Graph with tikz does not work

[KingOnline1]

Hallo community,

I'm new here and I don't know, if I'm in the right section. In that case: I'm sorry and I need advice.

Ok, now my problem:
I want to try to make some graphs in \latex. Especially a directed graph. I've found a example, which I thought to use and adabt to my problem. I've tried so much and done a lot of research, but I've found nothing, which is realy helpfully.

The Example I used is the followed

I don't now what to do.
Need Help, please?

I use MikTex and Win 8.1.

If you have some other solutions which work better, I'm welcome every idea.

Thank you very much for your help.

Welcome to the forum!

The error message shows, that you did not use the required LaTeX compiler. I guess you used pdfLaTeX. You need to change your editor setting to run LuaLaTeX.

Hello Stefan_K,

thank you very much for your quick reply.
But I don't know how to change that. I use Sublime3 to create my pdfs.

Hello Stefan_K,

I've found it yet. I used TexStudio. Now it works.
Thaaaaaanks a lot

[Stefan Kottwitz]

Great, that it works!

By the way, we are big friends of TikZ, so let us know if you got further questions.

Hi Stefan_K,

you are great. Do you speak german?
I want to go more familiar with it. Do you have some good turtorials for the beginning?

Buuuuut, indeed, I've got another question

Run LaTeX here

I get an error when I compile it. Now I use TexStudio.

Error:
Zeile 30: Missing \endcsname inserted. }
Zeile 30: Missing \endcsname inserted. }
... (this occures a lot of times)

I guess it is because I use mathematical expressions. Numbers and letters work.

Thanks a lot for your help, again.

[Stefan Kottwitz]

Do you speak german?

Yes, I do. We could also continue in German at our German partner site TeXwelt.de. We do much TikZ there. See: examples.

I want to go more familiar with it. Do you have some good turtorials for the beginning?

The TikZ manual contains some tutorials, I don't know others. But you can learn by doing and working together on code on TeXwelt.de oder here. Same mantainer.

I can take a look at the code of your previous post, it just takes some minutes until I'm on the computer again.

Stefan
