I have used \ncbar before with success and it worked perfectly however the following code:


Produces me the following:


The angleB=-90 is not taken into account. The \ncdiag works just fine. I use TeXmaker on a Linux machine and I compile with LaTeX + dvips + ps2pdf.

  • Can anyone reproduce it? Jul 10, 2012 at 14:44
  • When you run the above code you also get the wrong angle or is it as it is supposed to be? Jul 10, 2012 at 15:06
  • I thought so but apart the fact that I remember me using it an example of it can be found here link to pdf file Jul 10, 2012 at 15:24

    @VagelisBebelis: you can get such documents with running texdoc psmatrix. No need to load it from the net, it is already present on your computer.

from the documentation:

This node connection consists of a line with arms dropping “down”, at right angles, to meet two nodes at an angle angleA. Each arm is at least of length armA or armB, but one may be need to be longer.

You are looking for \ncangle[angleA=90,angleB=-90,arrows=->]{A}{B}

  • makes no difference, you can use angle or angleA. Important is only that angleB is not of interest

  • Indeed \ncangle did the trick. Thanks for your help. Still though I'm sure that \ncbar also takes two angles as arguments. Jul 10, 2012 at 16:19
  • no, \ncbar never used both angles.

  • In this example \ncbar uses both angles: \documentclass{article} \usepackage{pst-all} \begin{document} \begin{pspicture}(0,1)(4,-2) \begin{psmatrix}[emnode=r] \psset{arrowscale=2} Verbinde {\rnode{A}{KnotenX}} mit {\rnode{B}{KnotenY}}! \end{psmatrix} \ncbar[nodesep=3pt,angleA=-90,angleB=90,linecolor= red,arrows=<->,arrowscale=2, arm=0.8]{A}{B} \end{pspicture} \end{document} Jul 11, 2012 at 13:49
  • set angleB to something else, eg 45 and you'll see that nothing happens! angleB=90 would be a connection from above and not below if the angle would be taken into account.

Recall that the arms must be parallel then only certain angles that produce parallel arms are valid.

angle is the only valid option for \ncbar to change the direction. Both angleA and angleB are not used even though angle=angleA.

  • In documentation I find \ncbar connecting words using this notation though. It might be problematic because I use psframeboxes? Jul 10, 2012 at 15:38
