[pstricks] Drawing state diagrams

[Runar Gjelsvik]

That worked fine, thanks. But I get another problem:

When I want to add labels to the node connections all the labels are
placed on top of each other just right of the StoreRegs node. I've tried
adding [npos=xx] but it has no effect.

Runar

\psmatrix[mnode=circle,colsep=1,radius=10mm]
& & & \xst{ReadADC} \\
\xst{LoadFrame} & &  \xst{Idle} \\
& & & \xst{StoreRegs}
\endpsmatrix
\psset{shortput=nab,arrows=->,labelsep=3pt}
\small
\ncarc[arcangle=40,border=3pt]{2,3}{1,4}
\ncarc[arcangle=80,border=3pt]{1,4}{3,4}^{labelB}
\ncarc[arcangle=40,border=3pt]{3,4}{2,3}
\ncarc[arcangle=40,border=3pt]{2,3}{2,1}^{labelC}
\ncarc[arcangle=40,border=3pt]{2,1}{2,3}

the default for C
