[pstricks] ncangle variant is needed

[Juergen Gilg]

Hi Boris,

maybe you could try \ncbar, like

\begin{pspicture}(5,4)
  \psset{angle=90,armB=-1.5}
    \Cnode[radius=0.2](2.5,3.5){A}
    \Cnode[radius=0.2](0.5,1){B1}
    \Cnode[radius=0.4](1.5,1){B2}
    \Cnode[radius=0.6](2.6,1){B3}
    \Cnode[radius=0.8](4,1){B4}
   \ncbar{B1}{A}
   \ncbar{B2}{A}
   \ncbar{B3}{A}
   \ncbar{B4}{A}
   \Cnode[radius=0.2,fillstyle=solid,fillcolor=white](2.5,3.5){A}
 \end{pspicture}

and make the arm negative...

Seems to work.

Maybe Herbert is inspired to do that more elegantly...

Regards,

Juergen
