Document Classes ⇒ pst-node - problem with labels

[ororo]

Hello everybody.
I am trying to use pstricks, and in particular pst-node.

All commands work, *but* the commands to position labels on the edges:

\ncline{A}{B} \ncput{label}

creates an edge and then puts the label on the node A, instead then on the edge (A,B).
The same happens with \naput, \nbput, \tvput, ...

Somebody has some idea? thanks a lot!

Hi ororo,

welcome to the LaTeX Community board!
I used those commands similar without problems. Can you give us a minimal working example, that is compilable and shows the problem? Then it would be easier for us to test, to look for the problem and probably to provide specific help.

Here is a little example:

\documentclass{article}
\usepackage{pst-node}

\begin{document}

$$\begin{psmatrix}[rowsep=1,colsep=1]
& A & [name=upper] B \\
& [name=lower] C & D
\end{psmatrix}
\ncline{->}{lower}{upper} \naput{label}
$$

\end{document}

I expected the label "label" would appear over the arrow, but it doesn't (see attachment).

Hi ororo,

did you convert it to ps and viewed it with a postscript viewer? With dvi you cannot expect the right output. My result:

ps.png (1.58 KiB) Viewed 5272 times

Thank you Stefan! sorry my problem was really stupid!

So I cannot use pstricks inside a dvi? there is no way to make a dvi?

Hi ororo,

pstricks produces postscript code that will be embedded inside the dvi document. Some dvi-Viewer may show the embedded postscript code, if they can interpret it, like KDVI. You can work with pstricks and dvi, but at the end there should be a conversion to postscript for best results.
